Power Meter pulse logger with ESP8266 running NodeMCU
ESP8266 Low Power Solutions About This Guide This document introduces ESP8266 sleep mode and low-power solutions with the following topics: Release Notes Chapter Title Subject Chapter 1 Overview An overview of ESP8266 sleep mode. example of the applications is Pulse Width Modulation (PWM) light that needs real-time CPU control.
ESP8266 Interrupt Driven Meter Monitor - Hackadayio
/7/2011 Print. Go Down. Pages:  Topic it takes a record of Timer0 in the ISR, and then compares the time to the next pulse that comes in. It then does a calculation and determines how many pulses there would
ESP32 Arduino: Timer interrupts – techtutorialsx
Then some simple software picks up the pulses via an Interrupt handler, and increments a counter. The counter is sampled every minute and then reset, the result is sent via a TCP connection to the receiver. Pulse Detect line to ESP8266 - I'm using GPIO in my sample circuit - but have to switch to GPIO 2 as it makes reprogramming tricky

Power Meter pulse logger with ESP8266 running NodeMCU This device is installed in my home to monitor the usage of electricity. It counts the pulses from the meter and produces a log file with number of pulses and a time stamp that can later be analyzed.

ESP8266 PWM revisited (and reimplemented) – May you live
1/4/2018The Pulse-Counter-interface of ESPEasy also produces/provides a value Time. What is the content of this value Time? If the ESP8266 is connected to an S0-interface is there any meaningful application of this Time-value e. g. related to calculation of Usage ?
ESP8266 Projects - Benlo
Reads a pulse (either HIGH or LOW) on a pin. For example, if value is HIGH, pulseIn() waits for the pin to go from LOW to HIGH, starts timing, then waits for the pin to go LOW and stops timing. Returns the length of the pulse in microseconds or gives up and returns 0 …
ESP8266 counting Pulse without Interrupt - forumarduinocc
Pulse Counter; Pulse Width Modulation (PWM) Hardware Accelerator; Conclusion. So, which module is best suited to your project? The ESP8266 is cheaper than the ESP32. Because it's an older module, it has a larger community/development ecosystem, and you may find it easier to find help with it online.
