# Arduino-sensorics
* Arduino ESP32 micro-controller programming
* Provides simple and clean library for
* reading of various sensors
* export data via WiFi to InfluxDB for visualization in Grafana, see my [raspi-sensorics](https://github.com/entorb/raspi-sensorics/) repository
* writing to various displays
* using a device_setup.h file to select the devices attached to that specific Arduino ESP32
* read data from MQTT
## Devices implemented so far
* Abstract device class that all other devices inherit from in [TM_Device_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_Device_Class.cpp)
* InfuxDB interface via WiFi in [TM_InfluxDB_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_InfluxDB_Class.cpp)
* BME280 sensor for temperature, humidity and pressure in [TM_BME280_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_BME280_Class.cpp)
* BH1750 sensor for illumination in [TM_BH1750_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_BH1750_Class.cpp)
* MH-Z19B sensor for CO2 concentration in [TM_MH_Z19_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_MH_Z19_Class.cpp)
* 7-segment 4-digit TM1637 display in [TM_7SegmentDisplay_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_7SegmentDisplay_Class.cpp)
* OLED display 128x32px and 128x64px in [TM_OLED_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_OLED_Class.h)
* RGB-LEDs: Ring and Single LED in [TM_LED_Ring_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_LED_Ring_Class.cpp)
## Arduino packages used
* [Adafruit BME280 Library](https://github.com/adafruit/Adafruit_BME280_Library)
* [BH1750](https://github.com/claws/BH1750)
* [ESP8266 Influxdb](https://github.com/tobiasschuerg/InfluxDB-Client-for-Arduino)
* [MH-Z19](https://github.com/WifWaf/MH-Z19)
* [TM1637](https://github.com/avishorp/TM1637)
* [U8G2](https://github.com/olikraus/u8g2)
* [(MQTT) PubSubClient](https://github.com/knolleary/pubsubclient)
## Achievements
* Learning basics of C++: inheritance, templates, ...
* Using pre compiler #define in device_setup.h file to select which classes are compiled to save time and memory
* Power reduction from 1W to 0.3W by
* Under-clocking the ESP32 from 240 to 80 MHz via setCpuFrequencyMhz(80) in ([TM_ESP32_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_ESP32_Class.cpp)
* Enabling WiFi modem sleep via esp_wifi_set_ps(WIFI_PS_MODEM) in [TM_InfluxDB_Class.cpp](https://github.com/entorb/arduino-sensorics/blob/main/libraries/TM/src/TM_InfluxDB_Class.cpp)
* OLED display: implemented bar chart
* Standalone CO2 traffic light for our kindergarden and school
* offline
* in proper case
* using display and traffic light for visualization
* see German [Bauanleitung](https://github.com/entorb/arduino-sensorics/blob/main/CO2-Ampel-Bauanleitung.md)
* Experiment with display devices
## Next steps
* Design and build cases via CAD and CNC
* Add more sensors
