WIFI Temperature and Humidity Sensor - Internet Of Things (IOT)
This WIFI enabled device connects directly to your WIFI router so you send temperature and humidity readings to PrivateEyePi, or another monitoring application. It is fully assembled and requires no soldering. Connect it to power and it will advertise itself as a wireless access point. Configure it through a web browser using its easy to use config application. Once configured it will connect to your WIFI network which will give it access to the internet and the PrivateEyePi, or other. server.
Features:
- Easy to configure web interface. No programming or soldering skills required. You do not need the internet to configure the device. Connect to it directly from any WIFI device (e.g. PC, phone tablet…)
- Cyclic temperature transmission mode with configurable send interval
- Supports both Celsius or Fahrenheit temperature readings
- Sleep mode allows it to be run from battery power
- Configurable temperature delta threshold allows the device to monitor the temperature and only transmit when the current reading exceeds the previous reading by a configurable amount. This feature is very useful for saving battery power
- Powered either by USB Mini cable (4.5V DC to 7V DC input) or battery connection (2.5V to 3.5V) via the 2 pin battery connection plug
- Fully programmable using the Arduino or LUA development environments
- DHT22 Temperature and Humidity sensor is used to detect the temperature and humidity. Measures temperatures from -40°C to +80°C. Fahrenheit equivalent is -67°F to +257°F, ±0.5°C accuracy. Measures humidity from 0-100%RH with 2% across range.
-
**Note: The operating temperature for the WiFi Temperature sensor is -30F to +125.6F, -34C to 52C. If you need the larger range, select the External Sensor option.
- Although the sensor is highly accurate (±0.5°C accuracy) you can calibrate the temperature reading using a configuration in the WIFI sensor app
- The device supports dual WIFI mode allowing it to be WIFI access point and a WIFI client at the same time. A WIFI access point advertises itself through an SSID and can be connected to via any device or computer that has WIFI.
External sensor option:
- Sensor can be mounted external to the WIFI module
- 9" wires can be extended if required
- Soldering required. 3 of the 4 wires need to be soldered to the board (see external wiring picture)
Required, but not included:
- Mini USB cable and power supply (older cell phones used mini USB, so you may already have one in the bottom of a drawer)
- 5V to 7V power supply. Any USB power supply will work.
- Battery pack (optional)
