Description: 1. The module chip uses PCF8951 2. The module supports external 4-channel voltage input acquisition (voltage input range 0-5v) 3. The module integrates the photoresistor, which can capture the ambient light intensity with AD 4. Module integrated thermistor, can collect accurate temperature value of environment through AD 5. Module integrates 1 channel 0-5V voltage input acquisition (adjusts input voltage via blue potentiometer) 6. The module has a power indicator (the indicator will light when power is supplied to the module) 7. Module with DA output indicator, when the module DA output interface voltage reaches a certain value, it will light DA output indicator on the board, the greater the voltage, the greater the brightness of the indicator; 8. Module PCB size: 3.6cm x 2.3cm/1.5 x 0.9inch 9. Standard double panel, thickness 1.6mm, beautiful layout, surrounded by holes, aperture: 3mm, easy to fix. Specification: 1 single power supply 2.
