Realtime Pool/Spa Solar Temperature Sensor

PDFRealtime Pool/Spa Solar Temperature Sensor - Wemos D1 Mini 18650 TP4056 BME280 DS18B20
I wanted an enclosure to house multiple sensors, a battery, and a charging circuit. The enclosure could then be mounted to the back of a generic 5v solar panel. Having two DS18B20 probes lets me take temperature measurements of two bodies of water, and the BME280 will give us the ambient temperature, barometric pressure, and humidity. Ultimately the wemos will be running Tasmota and reporting back to Home Assistant (let me know if you need help with that).
The original design of the Wemos 18650 Sensor Box Mk2 by GrOhm was the form factor I was looking for, I just made a few tweaks using Fusion 360 including:
- Battery side
- Battery holder feet
- Bottom vent charger
- Top vent
- 4mm hole for solar panel input
- Fillet on rails for tolerance
- Sensor side
- Top vent
- Top mount for BME280
- Bottom mount for Wemos D1 Mini (borrowed from WeMos D1 mini case by @Murdoc
- Bottom mount for DS18B20 breakout
- Fillet on rails for tolerance
