Battery-powered IOT devices with ESP. Unlike BLE, WiFi is not designed for battery powered devices. Nevertheless, with a few tricks it is possible to operate a measuring device (for example a weather station) with a battery pack for more than one year. This is, however, only possible if the ESP is sent to sleep most of the time (deep sleep mode). The lifetime of the battery depends essentially. The ESP-01 should be scanning for Wi-Fi networks and reporting the results in the Serial Monitor window, as shown in the example below. You should see your own network in the report, and all other networks that are within range of the ESP-01. The numbers in parentheses show each network's signal strength, and because the numbers are negative, lower numbers represent stronger signals. The Door. 49 thoughts on Minimizing ESP8266 Battery Drain So, I used the ATTIny to monitor the doors and reset the ESP (so it would send an email) when necessary. All told, my setup, ESP, ATTIny. Why Battery Level Monitoring is Important. Have you experienced building a battery-operated project then suddenly it won't work because it needs to be charged? We all know that batteries come with a certain voltage limit. Exceeding or completely losing the battery's voltage can lead to a lot of frustration, component damage, or data loss. So. If you can reduce the timings and optimize your network, you can then organize a schedule to monitor and change or recharge batteries. An ordinary 200 mA solar panel is under 5$ and its enough to recharge a AA lithium between the 1 hour interval. The highest peek for ESP8266 is somewhere between 180-220 mA but it last only 1.5-3s.
