# ESP32-based Environmental Sensor
|
||||||
|

||||||
|
|
||||||
|
A simple temperature and humidity sensor node using an ESP32 and a Si7021 sensor element running of a 18650 LiIon battery cell.
|
||||||
|
The sensor outputs the data to an influxDB instance, which must be reachable via HTTP.
|
||||||
|
|
||||||
|
To save energy, we use a lower CPU frequency.
|
||||||
|
But this requires compiling the core framework again with the changed settings (see below).
|
||||||
|
|
||||||
|
This repository contains the code running on the ESP32, as well as the PCB and case design.

The [esp32-idf](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html#installation-step-by-step) is needed to compile software for the ESP32.
|

## Battery Life
|
||||||
|
The hardware was designed with two options to drop the battery voltage to a level, which can be fed to the ESP32: A voltage regulator or a simple diode.
|
||||||
|
|
||||||
|
A test with increased data rate (for a shorter test duration) resulted in a slightly better battery life using the voltage regulator.
|
||||||
|
Using a measurement interval of 30 seconds and a WiFi connection interval of 3 minutes, the 2500mAh LiIon (3.7V) battery lasted 30 days with the diode and 36 days using the voltage regulator.
|
||||||
|
In real-world application, a battery life of about 9 months can be expected (with good WLAN reception).
|
||||||
|
|
||||||
|
The selected voltage regulator has a quite low drop-out voltage and more importantly a low leaking current during the deep-sleep phases, which have a very low current needed by the ESP32.
|
||||||
|
In comparison a diode has no leaking current at all, but a more or less fixed voltage drop.
|
||||||
|
|
||||||
|
The benefit of the voltage regulator is, that the battery voltage range can be exploited further than what can be done with the diode.
|
||||||
|
The lowest operational battery level was 3.2 V using the diode and 2.8 V using the voltage regulator.
