Can i connect High Sensitivity Water sensor (REES52) to Bolt WiFi module.
It has 3 pins - output ,vcc, and gnd
REES- SR037 works between 3 and 5V. So you can connect it to either 3.3V or 5V.
But I would suggest you use the 3.3V point as it gives a regulated supply. As the output it analogous, there won’t be any difficulty in connecting it to A0. But make sure Bolt is kept at a safe distance from moisture. You can use a Breadboard fro that.
