This is a case for a pms5003 sensor and all the necessary parts to make in functional. I tried to make it modular so you kan modify a part of the case for your own components.

components used:

• heltec_wifi_lora_32
• am2301 temp/humidity sensor
• PMS5003 particle sensor
• Power supply from an old ChromeCast v1
• ESPhome software for integration with Home Assistant

note: I noticed that the temp sensor reports too high temperatures. It could be a faulty sensor or the actual temp inside the casing.
