ESP8266-DHT22 WeekEnd Project

Teste com os sensores DHT11/DHT22, captando a temperatura e humidade no IFMG Campus Formiga

Outside temperature & humidity of a DHT22 sensor running on an ESP8266 with solar charger.

Data from DHT22 sensor

Monitoring the outside temperature using a WiFi connection with a Wemos D1 microcontroller and a DHT22 sensor

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.
