Humidity, Pressure, Temperature 0 ~ 100% RH I²C, SPI ±3% 1 s Surface Mount The BME280 integrates three sensors—temperature, relative humidity, and pressure—along with a high-performance digital interface. It communicates via I²C or SPI, making it easy to interface with microcontrollers like Arduino, ESP32, and STM32. It is designed for low power consumption, making it suitable for battery-powered applications such as portable weather stations and smart home devices. Key Features Environmental Sensing Measures: Temperature Relative Humidity Barometric Pressure Enables altitude estimation based on pressure readings High Accuracy Temperature: ±1.0°C (typical) Humidity: ±3% RH (typical) Pressure: ±1 hPa (typical) Low Power Consumption Typical current: ~0.6 µA (sleep mode) ~3.6 µA (measurement mode) Ideal for battery-operated devices Communication Interfaces Supports: I²C (up to 3.4 MHz) SPI (3-wire / 4-wire) Easy integration with most microcontrollers Compact Package Small footprint: 2.5 × 2.5 × 0.93 mm LGA package Suitable for space-constrained designs Built-in Features Factory-calibrated coefficients stored in NVM Configurable oversampling and filtering Integrated ADC for high-resolution measurements #commonpartslibrary #sensor #humidity #pressure

Bipolar (BJT) Transistor NPN 40V 600 mA 300MHz 300 mW Surface Mount SOT-23-3 (TO-236) The MMBT2222ALT3G is a NPN general-purpose bipolar junction transistor (BJT) manufactured by onsemi, designed in a SOT-23 surface-mount package. It is the SMD version of the well-known 2N2222A transistor family, used for switching and signal amplification in compact electronic circuits. It is widely used in industrial, automotive (AEC-Q101 qualified variants), and general embedded systems due to its reliability, small size, and good electrical performance. Key Features NPN General-Purpose Transistor Suitable for switching and low-power amplification Collector-Emitter Voltage (Vceo) Up to 40 V Collector Current Up to 600 mA Power Dissipation Around 225–300 mW (depending on package conditions) High Frequency Performance Transition frequency up to ~300 MHz DC Current Gain (hFE) Typically ~100 at moderate currents Low Saturation Voltage Efficient switching performance for digital circuits SOT-23 Surface-Mount Package Compact footprint for modern PCB designs Wide Temperature Range Typically -55°C to +150°C RoHS / Lead-Free Compliant Environmentally compliant manufacturing Typical Applications LED switching circuits Relay driver stages MCU signal interfacing (Arduino, ESP32, etc.) Small motor drivers General signal amplification Automotive and industrial control circuits Important Note MMBT2222ALT3G = SMD version (SOT-23) Equivalent to 2N2222A (TO-92 through-hole version) in function, but not in physical package. 2N2222A SOT-23 #commonpartslibrary #transistor #bjt
