Autonomous sensors with ESP32

Plantower dust sensor PMS7003

Measure air pollution with autonomous sensors in any location.
I used the following components:
– ESP32 Mini
– 6V solar cell
– MAX17043
– LiPo 3.7V 2000 mah
– PMS7003/PMS5003/PMSA003
– Bosch BME280

Data are transferred by WLAN to my mosquitto MQTT server
every 5 minutes. I made successful tests with LILYGO TTGO
T-SIM7000G / T-CALL transferring data over GSM. Updated over
OTA completes those systems. If battery is too low collecting
data is stopped for 12 hours.

Data send to the MQTT server and saved with ESP32 ID in database

Other sensors like BH1750 / TSL2591 / VEML6075 working with the same method

Some measuring for nuclear radiation and co2

If you see here values greater than 100 cpm you should leave the area.
It is possible that something happens in Tihange.

The “adult” zone

They love children in this Club but quietness as well. Therefore they arranged an adult pool and an adult area for dinner.
