LDR (Light Dependant Resistor). Dark resistance >20M Ohm, light <80 Ohm. The two outer pins connect to the LDR. A fixed 10 K ohm resistor connected between the middle pin and the ‘S’ pin is included on the module. This simplifies the building of a measurement bridge circuit.
A microphone module featuring a high-sensitivity large-format electret capsule. Output ‘DO’ (active high) is switched when the sound level exceeds a preset level. A pot allows adjustment of the level. The analog output signal is available at the ‘AO’ pin.
This is a breakout board that contains MMA8452 IC, which is a 12-bit resolution 3-axis accelerometer. It can detect ±2g/±4g/±8g accelerations. It has I2C communication interface.
