We bring you yet another easy to emulate, easy to initiate DIY. Instructables user MisloElectronics has created a wireless thermometer that measures the indoor and outdoor ambient temperature. The device is neat and works. It can be constructed in two parts. The first one is a transmitter system, made of one digital temperature sensor and a transmitter module. The second part is the receiver system, comprising an LCD screen, an analog sensor and a receiving module.
Two arduinos of any version were required to configure this one. A DS18B20 digital temperature sensor, a LM35 analog temperature sensor, a LCD 16×2 for displaying temperature readings, and a RF 433MHz module were employed. Since the sensors are factory calibrated, they are reliable. The software code for arduino is made available by the user for free.
As said, this one is easy to emulate and shouldn’t take more than an hour to build this one. So when are you building your own?
