WIFI Temperature and Humidity Sensor - Internet Of Things (IOT)
This Wi-Fi-enabled device connects directly to your Wi-Fi router, allowing you to send temperature and humidity readings to Monitoring.JemRF.com 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 configuration application. Once configured, it will connect to your Wi-Fi network, giving it access to external servers.
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 Wi-Fi device (e.g., PC, phone, tablet).
- Cyclic temperature transmission mode with configurable send interval
- Supports either Celsius or Fahrenheit temperature readings
- MQTT support for an external broker of your choice.
- A configurable temperature delta threshold allows the device to monitor temperature and transmit only when the current reading exceeds the previous reading by a specified amount. This feature is handy for saving battery power.
- Powered either by a USB Mini cable (4.5V DC to 7V DC input) or by an external power source (3.5V - 5V) via the 2-pin connection.
- DHT22 Temperature and Humidity sensor measures temperature and humidity. Measures temperatures from -40°C to +80°C. Fahrenheit equivalent is -40°F to +176°F, ±0.5°C accuracy—measures humidity from 0-100%RH with 2% across the range.
-
**Note: The operating temperature for the WiFWiFimperature 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 Wi-WiFi, allowing it to act as both a Wi-WiFi access point and a Wi-WiFi client simultaneously. A Wi-Fi access point advertises its SSID and can be connected to via any Wi-Fi device or computer.
External sensor option:
- The sensor can be mounted externally to the WIFI module
- 9" wires can be extended if required
- Soldering required. 3 of the four 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 at the bottom of a drawer)
- 5V to 7V power supply. Any USB power supply will work.
Installation:
Specs:
- Dimensions 74mm x 55mm x 28mm
- 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
- -34C to +52C. Fahrenheit equivalent is -30F to +125.6F, ±0.5°C accuracy from -10°C to +52°C
- Can be programmed using Arduino or LUA development environments
-
Upgraded using a 3.3V FTDI cable
Optional: Extended-Range Antenna for a more extended range and around objects.
