Wireless weather sensor

The CMA wireless weather sensor is a compact, portable device for measuring various weather-related parameters, including temperature, humidity, air pressure, wind speed and direction, light intensity, and UV index. A wind vane and tripod are included for accurate and convenient measurements with the sensor.
The weather sensor is equipped with an OLED color display that shows sensor information and measured values. This makes the sensor suitable as a standalone measuring instrument.

The wireless weather sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).

Suggested geography and science experiments:

The weather sensor simultaneously measures primary parameters such as temperature, humidity, air pressure, wind speed and direction, light level, and UV index. Based on these basic measurements, many other weather parameters can be calculated or derived.
The following parameters can be derived from the primary values ??measured by the weather sensor:
  • Dew point — shows when condensation or fog will form
  • Absolute humidity — relates to “how much water is really in the air”
  • Vapor pressure deficit (VPD) — connects to plant growth and evaporation
  • Heat index — “feels like” temperature on hot days
  • Wind chill — “feels like” temperature on cold, windy days
  • Air density — links temperature, pressure, and wind energy
  • Wind power density — lets students estimate potential wind turbine output
  • Cloud base height (LCL) — a quick cloud formation predictor
  • Beaufort scale — easy wind speed classification without much math
  • UV exposure time — connects UV index to sun safety
  • Irradiance from illuminance — shows sunlight as energy, not just brightness
