This article explores different types of WiFi sensors, focusing on temperature, pressure, and humidity sensors. It compares WiFi temperature sensors, WiFi pressure sensors, and WiFi humidity sensors.

WiFi, short for Wireless Fidelity, signifies products that adhere to WLAN standards like IEEE 802.11a/b/g/n, etc.

WLAN offers a coverage range of approximately 30 to 150 meters and data transfer speeds from 6 Mbps to 150 Mbps, depending on the WLAN standard version, bandwidth utilization, and the number of antennas employed.

WiFi enables the transfer of sensor data to WiFi-enabled devices like laptops, desktops, smartphones, and tablets for further recording or analysis.

These sensors are equipped with WiFi transmitters that broadcast the recorded data over WiFi frequencies to WLAN-compatible devices, such as laptops, smartphones, or computers connected to a LAN with a built-in WLAN card.

WiFi Temperature Sensor

  • A temperature sensor with WiFi capabilities is known as a WiFi temperature sensor.
  • It utilizes a temperature sensor integrated into the device to measure the surrounding temperature.
  • Typically, it measures temperatures ranging from -40 to +85 degrees Celsius.
  • WiFi temperature sensors offer temperature measurements with an accuracy of approximately +/- 0.2 degrees Celsius.

WiFi Pressure Sensor

  • A pressure sensor equipped with WiFi functionality is referred to as a WiFi pressure sensor.
  • It measures barometric pressure using a dedicated pressure sensor.
  • The typical pressure measurement range is from 1 KPa to 110 KPa (equivalent to 10 mbar to 1100 mbar).
  • WiFi pressure sensors provide pressure readings with an accuracy of around +/- 2 mbar.

WiFi Humidity Sensor

  • A humidity sensor with WiFi capability is known as a WiFi humidity sensor.
  • It uses a humidity sensor mounted on the device to measure relative humidity (RH).
  • It measures RH in the range from 0 to 100%.
  • WiFi humidity sensors measure RH with the accuracy about +/- 2%.
