With a data logger several sensors can be used together to monitor the weather over periods lasting weeks. Suitable sensors include temperature, pressure, humidity, light or even a rotation sensor to check the wind speed. For serious work, involving months of weather recording, a dedicated weather station should be considered.
A data logger and sensors such as temperature, humidity and light sensors.
1. Connect the sensors to the data logger.
2. Position and fix the sensors in suitable places, for example, hang them out of the window. If the equipment is placed outside, keep parts of it in a polythene bag.
3. Start the data logger recording.
4. After the recording, connect the data logger to the computer and get the software to transfer the data from the data logger.
