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

BMP085 Pressure+Temperature and HTU21D Humidity and Temperature sensor readings with ESP8862

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.
