Add smart notifications to your project. This circuit board and case plus the included processor with our code is all you need to add wireless notifications to your product: short the pins on the white connector and you will get an alert! Use the included cable as is or cut it and connect to your own sensor. The connector we use is a JST XH 2.5mm 2-pin male. Important: device requires access to WiFi to send alerts. 3 AAA batteries required, not included.
