Feature
Size:36 x 15 x 7mm
Voltage:3.3-12VDC
Current:working
Interface:+-DO AO
DO digital quantity / AO analog quantity
Uses:to detect soil moisture
Principle:The soil moisture probe detects the humidity, and the voltage comparator determines the humidity. When the humidity is greater than the set value, the DO outputs a low level.
Instructions for use
1. “+ Inch is connected to the positive pole of the power supply, and “- Inch is connected to the negative pole of the power supply. Do not reverse the connection, otherwise the chip may be burned out. After the power is connected, the “P Inch power indicator lights up and the module works normally.
2. The blue potentiometer can be adjusted clockwise/counterclockwise to increase/decrease the probe detection sensitivity. Take the “thermal sensor Inch as an example. Assume that the default is 25°C trigger and the “DO Inch output is active low. After clockwise adjustment, the temperature will trigger below 25 °C. Counterclockwise triggers above 25 °C.
3. When the potentiometer is adjusted clockwise until the “S Inch output indicator is on, it indicates that the adjustment range has exceeded the test threshold, and the counterclockwise adjustment until the adjustment cannot be made exceeds the threshold. When adjusting, the threshold cannot be exceeded, otherwise it will not work properly. When the potentiometer is used only for the inchDOinch port, it is not associated with the inchAOinch output.
4. The “AO Inch output is analog (voltage), which can be directly detected by the AD port of the MCU.
