ZJ-S201 Liquid Flow Sensor The ZJ-S201 liquid flow sensor enables measurement of low-viscosity fluid flow in the range of 1 to 30 l/min. The sensor output is a pulse signal whose frequency is proportional to the flow rate. The device is based on a rotating turbine with a magnet and a reliable Hall sensor. The product works great in automation systems - it is suitable for ESP8266, for ESP32, for Arduino, and for Raspberry Pi.
