Applications
Temperature is one of the easiest sensor projects to start on and have any uses. Applications may include:
- monitoring the temperature of a smart bee hive, rabbit hutch, chick coop, compost heap, worm farm, aquarium or wetland
- experimenting with concepts related to energy efficient building construction
- temperature compensation for other sensors (sensor values may change with changes in temperature)
- making a weather station
Types of temperature sensors
The are two common temperature sensors that are used.
- An internal temperature and humidity sensor is the DHT22. This is included in all sensor project to monitor temperature and humidity conditions within the sensor housing. If the temperature gets too hot or too cold within the sensor housing this may shorten the life of the equipment and the batteries.
- An external temperatures sensor is the DS18B20. External sensors are typically water proof and have a longer cable. They can be used to monitor a range of interesting discovery learning projects.
