Smart Mould Risk Detector Prototype

I am assembling a proof-of-concept device that spots mould risks before they become a problem. The core is an ESP32 with Wi-Fi, a BME280 for temperature and humidity, a wall-surface moisture probe, and (if you think it adds value) a simple airflow input. Your job is to turn that parts list into a fully working prototype I can hold in my hand.

I’m looking for help to develop a working prototype using:

* ESP32 (WiFi)
* Temperature + humidity sensor
* Moisture sensor (surface/wall)
* Basic airflow logic (optional)

Requirements:

* Device reads sensor data
* Calculates a simple mould risk score
* Sends data to a mobile app/dashboard (Blynk or similar)
* Triggers alerts when thresholds are exceeded

Deliverables:

* Working prototype (hardware + firmware)
* Clean, documented code
* Setup instructions so I can replicate it

Optional:

* Advice on improving for manufacturing later

Timeline:

* 1–3 weeks

Please include examples of similar IoT projects.

Timeline is tight—ideally the first functional build in week one, polish and documentation by week three at the latest. When you reply, please link to one or two similar IoT projects you have delivered (ESP32, sensor fusion, or Blynk work is most relevant). I am ready to start as soon as I find the right partner.
