Specifications:
- The module supports external voltage input of the 4-way acquisition (voltage input range of 0-5v)
- The module integrated photoresistor by AD collection precise value of the ambient light intensity
- Module integrated thermistor by the precise value of the ambient temperature of the AD acquisition
- Module integrated 1 channel 0-5V voltage input acquisition (the blue potentiometer to adjust the input voltage)
- Modules with power indicator (for the module power supply indicator lights)
- Modules with DA output indicator, when the module DA output interface voltage reaches a certain value, will be lit panel the DA output indicator, the higher the voltage, the more obvious indicator brightness
