BME280 is a digital humidity, pressure and temperature sensor from Bosch Sensortec in an LGA-8 package — for weather stations, indoor navigation and IoT environmental monitoring. Three sensors in one 2.5 mm package is the selection point: humidity, pressure and temperature from a single I2C device, which is why it became the default environmental sensor for maker and IoT designs. Selection advice: for humidity plus temperature only, the BME280 also covers pressure you may not need — confirm whether your application needs barometric pressure before choosing between this and humidity-only alternatives. Verify your supply voltage and interface (I2C/SPI) against the datasheet.

Bosch Sensortec lists BME680 as a 4-in-1 environmental sensor combining gas, pressure, temperature and humidity sensing in an 8-pin LGA 3.0 × 3.0 × 0.93 mm package, with I2C and SPI interfaces, 1.71–3.6 V supply. Four sensors in one 3 × 3 mm package is the procurement advantage: gas (VOC/air quality), pressure, humidity and temperature from a single qualification, a single footprint and a single sourcing line — replacing up to four discrete sensors. Selection advice: the gas-sensing element needs burn-in and baseline calibration in your firmware — confirm your software handles the BME680 gas baseline algorithm before committing. For pressure/humidity-only designs, the BMP280/BME280 may be cheaper; choose the BME680 when air-quality data is genuinely required.

BMI270 is a Bosch Sensortec ultra-low-power 6-axis IMU — for wearables and hearables where every microamp counts: 16-bit triaxial accelerometer (±2/±4/±8/±16 g) plus 16-bit triaxial gyroscope (±125 to ±2000 dps) in a 2.5 x 3.0 mm LGA-14, with gesture, context and activity recognition running in a 30 µA ultra-low-power domain. The plug-and-play step counter is optimized for wrist-worn devices, and motion-triggered interrupts let the host stay in deep sleep until something actually happens. Selection advice: the BMI270 is the wearable-optimized member of the BMI260 family — for smartphone-grade performance the BMI260 suits better; for drone and robotics vibration robustness the BMI088 is the alternative. Two application-specific variants exist (gesture vs context/activity) — match the firmware variant to your use case. Parameters verified against Bosch Sensortec documentation and distributor listings.

BMP280 is a digital barometric pressure and temperature sensor from Bosch Sensortec in an 8-pin LGA package, for altitude estimation, weather monitoring, drones and indoor navigation. Its advantage is the combination of small size, low power and factory-calibrated digital output — pressure and temperature arrive over a digital bus with no analog signal chain to design. Selection advice: Bosch ships the BMP280 in a compact LGA that demands proper reflow profiling; confirm your assembly process handles LGA packages. For new designs, also check whether the BME280 (adds humidity) or BMP388 (newer generation) better fits your requirements — but they are not drop-in code-compatible, so the sensor choice must be fixed before firmware is finalized.

ACS37002LMABTR-050B5 is an isolated Hall-effect current sensor from Allegro MicroSystems in a 16-pin SOIC package, with a 50 A measurement range on tape and reel — for high-current motor drives, solar inverters and industrial power. The 50 A range in a standard SOIC-16 is the selection point: high-current isolated sensing without a bulky module or external shunt. Selection advice: the 050B5 code denotes the 50 A bidirectional variant — the ACS37002 ships in multiple ranges that are not interchangeable, so match the full ACS37002LMABTR-050B5 code. Confirm your current range, bandwidth and isolation requirements against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-05B-T is an isolated Hall-effect current sensor from Allegro MicroSystems in an 8-pin SOIC package, with a 5 A measurement range — for motor control, power supplies and overcurrent protection. The integrated Hall sensor with 2.1 kV isolation is the selection point: current sensing with galvanic isolation and no shunt resistor, so no power dissipation or high-side measurement headaches. Selection advice: the 05B code denotes the ±5 A range — the ACS712 ships in 5/20/30 A variants with different sensitivities that are not interchangeable, so match the full ACS712ELCTR-05B-T code. Confirm your current range and bandwidth needs against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-20A-T is an Allegro MicroSystems fully integrated Hall-effect linear current sensor in 8-pin SOIC (0.154 in narrow), tape-and-reel packing (TR) — ±20 A sensing range, 100 mV/A output sensitivity, ratiometric voltage output centered at 2.5 V, 5 µs output rise time, 80 kHz typical bandwidth, 4.5–5.5 V single supply, ±1.5% total output error at 25 °C, 1.2 mΩ primary conductor resistance, 2.1 kV RMS isolation between pins 1–4 and 5–8, −40 to +85 °C. The integrated copper conduction path is the selection point: current flows through the package itself, so sensing adds only 1.2 mΩ of series resistance — no external high-power shunt resistor and no isolation optocoupler needed for 2.1 kV RMS separation in motor control, SMPS, load monitoring and overcurrent protection. Selection advice: this is the bidirectional 20 A member — the ±5 A and ±30 A siblings differ in sensitivity and bandwidth, and the 20 A choice trades resolution against range, so match the range to your actual fault-current envelope. Allegro notes the ACS712 is not intended for automotive applications. Evidence: Allegro ACS712 datasheet and distributor listings confirm ±20 A, 100 mV/A, 80 kHz, 2.1 kV RMS, 8-SOIC and tape-and-reel packing. Match the full ACS712ELCTR-20A-T code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-30A-T is an Allegro Hall-effect linear current sensor in 8-SOIC — ±30 A bidirectional sensing, 66 mV/A sensitivity, 5 µs output response time, 80 kHz bandwidth, ±1.5% accuracy, 2.1 kVRMS galvanic isolation between the current path and the output, 1.2 mΩ internal conductor, 5 V single supply, ratiometric analog voltage output, tape-and-reel packing (T), -40 to +85 °C. The zero-insertion-loss sensing is the selection point: no external shunt resistor and no power dissipated in the sense path — the current flows through a 1.2 mΩ copper path while the output voltage is proportional to AC or DC current. Selection advice: this is the ±30 A version — the ACS712 also comes in 5 A and 20 A versions with different sensitivity, so match the full ACS712ELCTR-30A-T code to your current range. The FILTER pin lets you set bandwidth with an external capacitor. Evidence: Allegro ACS712 datasheet and distributor listings confirm ±30 A, 66 mV/A, 5 µs, 8-SOIC and reel packing. Match the full ACS712ELCTR-30A-T code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADP5200 is a Panasonic PS-A series compound pressure sensor in 6-pin SMD module — ±100 kPa rated pressure (±200 kPa proof), amplified 0 V to 4.5 V analog output, ±1.25 %FS accuracy, temperature compensated, 5 V drive, -10 °C to +60 °C. The amplified temperature-compensated output is the selection point: it drops straight into a microcontroller ADC with no external instrumentation amplifier or calibration network. Selection advice: ADP5200 is the ±100 kPa SMD code — the ADP5100 is the DIP twin and the ADP5240 covers 100 kPa gauge; match the pressure type (compound vs gauge) to your medium. Honest lifecycle note: this series is in Last Time Buy — available for existing designs, so confirm the lot and consider a lifetime buy for ongoing production. Evidence: the Panasonic PS-A official catalog confirms the pressure range and package codes.

ADXL345BCCZ is a digital three-axis accelerometer from Analog Devices in a 14-pin LGA package — for motion detection, tilt sensing, tap/double-tap input and free-fall detection in handheld, wearable and industrial devices. Its advantage is the built-in activity/inactivity and tap sensing: motion events wake the host from sleep without continuous polling, which cuts system power in battery designs. Selection advice: the CCZ suffix denotes the LGA-14 package on tape and reel — the ADXL345 ships in several packages, so match the full code to your layout. For new designs, compare against current-generation accelerometers on power and noise if your budget allows; for existing designs, match the code exactly.
