Have you ever worry about your loved baby is covered well at night?
Now, we don’t need to worry about it anymore as we can DIY a temperature monitor and alert gadget by using Bluetooth 4.0 BLE sensors tag with bed programming.
The BLE sensor tag has built-in temperature sensor, and we can place inside the comforter. When baby kicks off the comforter, the temperature inside the comforter will decease.
The smartphone that lodes the APP shown below acts as the bluetooth gateway. It will check the temperature reported by the BLE sensor tag, and if it fails below a preset threshold, it will alert the watch worn on the parent by turning on the vibrator inside the watch.
