IntroductionThe module integrates MCP3432 A/D converter chip. The module can provide analog input function for Raspberry Pi and provide high accuracy analog input for Arduino.
MCP3424 is one of the low noise and high accuracy 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) converter family members of the MCP342X series. Its characteristic is:
Self calibration of internal offset and gain per each conversion.
User can select the PGA gain before the analog-to-digital conversion takes place. This allows the device to convert a very weak input signal with high resolution.
The device have two conversion modes:

(a)One-Shot mode: the device performs a single conversion and enters a low current standby mode automatically until it receives another conversion command.
(b)Continuous mode: the conversion takes place continuously at the set conversion speed.
Applications
Temperature Sensing with RTD, Thermistor, and Thermocouple
Bridge Sensing for Pressure, Strain, and Force
Weigh Scales
Battery Fuel Gauges
