Temperature Humidity sensors are one of the most common and widely used sensors with Arduino and other IoT platforms. There are so many use cases where a temperature humidity sensors can be used to detect potential problem like frozen pipes, broken freezers, malfunctioning air conditioning, water/humidity detection in crawl spaces and much more. In this IoT Arduino wireless temperature Humidity sensor project we will interface a long range wireless temperature humidity sensor with Arduino. These readings can be used to set an alarm or to send an alert.
