2331211-1 is an AmbiMate MS4 Series Sensor Module Development Kit designed for rapid prototyping and integration with Raspberry Pi and Arduino platforms. This kit includes the AmbiMate MS4 sensor module (2314277-1) featuring four core sensing capabilities: PIR motion detection, ambient light level measurement (0-1024 Lux), temperature sensing (5°C to +50°C with ±1°C accuracy), and relative humidity monitoring (5% to 95% RH with 3% accuracy). The module operates on 3.3 VDC input with I2C communication protocol and features an interrupt-driven event pin for real-time motion detection. With a compact design (32mm x 16mm) and vertical header configuration, this development kit is ideal for indoor lighting, building automation, connected home, air quality monitoring, and workspace comfort applications.
