Before we proceed with detailed breakdown of code, connect your Arduino to PC, compile below code and upload it to the Arduino. Create a Hardware Gateway (Arduino receiver based) to receive and do job with received information from sensors. HI new to element14 and hooked with tbhs. Is there a way to monitor the battery that feeds an esp8266 in a portable project? I have been meaning to implement that feature into my project so that i can be warned when the battery runs low on juice but i don't know if the esp has some kind of onboard sensor to do that. The Sketch. Wire the project together as shown in the diagram (and photograph) above. when using a LiPo battery), or else report battery voltage visually on screen in some application. I'm trying to come up with a circuit to monitor my car battery safely. Anyway, since I only carry a single battery, I need to know how much consumption is there, what is the charging current when applicable and the battery voltage. Our voltage can range as high as 20vdc in certain situations (open circuit pv voltage), so we designed a voltage divider that would provide 5v at 20v battery voltage, and less at various lower voltages. If you can monitor the battery voltage, when the battery will run out, you can replace the battery with a spare battery.
