YF-S201C Water Flow Sensor Features YF-S201C is a sensor used to measure the water flow. This water flow sensor mainly consists of a plastic valve body, rotor assembly, and hall effect sensor. This module works based on the hall magnetic effect. So when water flows through the rotor assembly, the rotor will rotate and the hall effect sensor will produce an electric pulse. By counting these generated pulses, the amount of water passing through the sensor can be calculated.The measuring range of water fl...

CJMCU-0201 Double Touch Sensor Features A touch sensor is a type of switch that only has to be touched by an object to operate. Touch sensors work completely similar to a switch. This sensor has two separate pads and can be used as two separate switches. Note When this switch is subjected to touch, the output voltage will be HIGH, otherwise it is LOW. Note The output current is very low (about 40 mA). If you want to connect a higher current device to this switch, you must add a rela...
