This module is based on a touch detection IC (TTP223B) of Capacitive type touch jog switch module . This module default output low, the low-power mode to mode; when a finger touching the corresponding position, the module will output high and returns low again touch. Mode is switched to fast mode; when for 12 seconds without touching
Fixed turn the lamp current to 0.1 times the value of the constant current (charge when used to identify whether the battery is full);
2. Increased input reverse polarity protection diode;
3. Using dedicated reference IC, and high-precision sampling resistor, so that the constant current is more stable, (20 degrees to 100 degrees, the constant current 1A, when the temperature drift of less than 1%).Particularly suitable for LED driver
*High-power LED constant current drive
*Lithium battery charger (including ferroelectric)
MICRO USB is an international standard, most smartphone data lines have adopted this interface,
wide range of uses, this module easily be converted to conventional DIP2.54mm pin,
a great convenience to your application!

soil humidity module to the environmental humidity is the most sensitive, generally used to detect soil moisture.
module in soil moisture can not reach the setting threshold, DO mouth output high level, when soil moisture more than setting threshold, module D0 output low level;
small plate digital output D0 can be directly connected with the single chip microcomputer, through the single chip microcomputer to detect the high and low level, thus to detect soil moisture;
