ESP8266 powered web server + LED control + DHT22 temperature/humidity sensor reading

Wednesday, November 26th, 2014

Martin writes: The ESP8266 System-on-chip (SoC) has recently came out of nowhere and has been taking by storm the IoT DIY world. It is a $4.50 Wi-Fi capable chip that has remarkable specs, obsoleting overnight a number of similar products that are out there. The price factor, availability of SDK...

Weather station

Tuesday, October 29th, 2013

Xose Perez of Tinkerman has written an article detailing the build of his weather station: Arduino FIO based weather station with a DHT22 temperature & humidity sensor and a BMP085 barometric preassure sensor. The whole sensor will be powered by a solar panel (doubling as irradiance sensor) and backed by a LiPo cell.

emonTH – Wireless temperature and humidity monitoring node

Friday, October 18th, 2013

Glyn Hudson over at OpenEnergyMonitor has developed this remote temperature and humidity monitoring node, the emonTH: The emonTH supports both the DHT22 (humidity and temperature) and DS18B20 either onboard or remote temperature sensor. The default software will search for the presence of either sensor at startup. If both sensors are found it will...
