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
Environmant sensor using ESP8266 WiFi processor and "CJMCU HTU21D BMP180 BH1750FVI Temperature Humidity Barometer Light Brightness Sensor"
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
ESP-01 DHT11 Temperature, Humidity, LED Light and ESP-01 Free Heap Monitor.
Temperature and Humidity data. Measured with SHT15 sensor. Updated using Arduino Uno - R3 + Ethernet Shield
