Receiver channel for D3 I/O changes

Receiver channel for D2 I/O changes

Receiver channel for D1 I/O changes

Este es el primer test usando NodeMcu y un servidor MQTT de esta forma se pueden enviar todo tipo de datos aplicado para el internet de las cosas IOT o para estacion de monitoreo climático Por Ing. Mario García

Testing ESP

First test of ESP8266 with NodeMCU firmware. Data are read from pressure sensor BMP085, humidity sensor DHT11, and temperature sensor DS18x20. Everything is powered with ATMEGA328p

Freezer-to-Frigidaire, ESP8266 powered freezer cell periodically shut down to stay within typical refrigerator temperature range (e.g. 2 to 5°C) A DHT22 inside the freezer is polled and a 5V relay and a cascaded BIG 220v SSR are switched accordingly.
