Monitoring the outside temperature using a WiFi connection with a Wemos D1 microcontroller and a DHT22 sensor
ESP8266 module sending data from an Arduino Uno which gets readings from a TMP36 temperature sensor.
ESP8266 running NodeMCU with a DHT11 to report humidity and a BMP180 to report pressure and temperature. The Sensor also reports battery voltage which is 2xAA batteries. Photo: http://imgur.com/hDpeNxj
