e-Air Environmental Sensor

The BroadLink ES-WIFI-5V has four basic functions; it is controlled with a wifi phone app:

• Air Quality: Detects harmful gases in the air (Hydrogen, carbon monoxide, methane, butane, alcohol, ammonia and other volatile gases).
• Temperature: Monitor temperature in real time around equipment, or just for general room temperature.
• Humidity: Monitor humidity in real time around equipment, or just for general room humidity.
• Light Levels: Monitor light levels, great for determining dawn/dusk
• Sound Levels: Monitor sound levels, detect people in room or equipment failure when no noise

The unit also has IFTTT capability (if-this-then-that) and it can connect to other devices on the network, such as the RF-IR blaster hub. For example, you could monitor temperature and turn on a heater with the SmartPlug device if it falls below a certain level.
