WIFI Temperature Sensor - Internet Of Things (IOT)
This Wi-Fi-enabled device connects directly to your WIFI router, so you send temperature readings to Monitor.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 config application. Once configured, it will connect to your Wi-Fi network, giving it access to internet servers and supporting multiple MQTT data formats, including a Home Assistant-compatible format.
Features:
- Easy to configure web interface. No programming or soldering skills are 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 both Celsius and Fahrenheit temperature readings
- 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.
- Battery level is transmitted every 10 temperature transmission cycles
- 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.
- DS18B20 temperature sensor is used to measure temperature. It measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F, ±0.5°C accuracy from -10°C to +85°C
- 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-Fi mode, allowing it to simultaneously act as a Wi-Fi access point and a Wi-Fi client. A Wi-Fi access point advertises its SSID and can be connected to via any Wi-Fi device or computer.
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.
- Battery pack (optional)
