ESP32 Frequency Counter using Pulse Counter and Remote Control modules
ESP8266 based pulse counter for S0 output from energy meter
Universal Sensor data transporter over MQTT. Sensor like water flow sensor (=pulse-counter), DS18B20 , INA219, 4-20mA, PMS5003, ...
GGreg20_V3 with Generic ESP32 with Tasmota Firmware and Berry script driver example
Very flexible device to integrate the smart home with water, gas, electricity meters etc. which provide pulse outputs.
This arduino code for STM32F411 will record a gpio's high and low duration for multiple pulses.
Provides nodes to access EWIO2 interfaces like IOs and metering - from Node-RED
