Plantower dust sensor PMS7003<\/figcaption><\/figure>\n\n\n\n

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<\/p>\n\n\n\n

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.<\/p>\n\n\n\n
