ow-Cost Bluetooth External Sensor Prototype

I’m looking for someone to build a low-cost prototype external sensor unit for my GrowlerZ iOvilus project. The idea is a small Bluetooth sensor hub that connects to an Android phone/app and sends live readings from external sensors. Prototype requirements: ESP32-C3 or similar low-cost Bluetooth/USB-C microcontroller External EMF/magnetometer sensor Ambient temperature sensor Humidity sensor Barometric pressure sensor Light/lux sensor Battery powered if possible, or USB powered for first prototype Simple 3D-printed or off-the-shelf enclosure Live sensor readings sent over Bluetooth BLE Basic documentation so my app developer can connect it to a Flutter Android app This does not need to be a finished commercial product yet. I’m looking for a working proof-of-concept prototype first, keeping the cost as low as possible. Please let me know: Whether you can build this Estimated cost for a prototype Estimated timescale What parts you would recommend Whether you can provide firmware/source code Kind regards, Stephen Lewis GrowlerZ Paranormal Tools
