About this model

An alternative housing for square-screen temperature and humidity sensors (compatible with the Tuya/smart home ecosystem). The original design relies on three AAA batteries — which drain within two weeks — and causes Ni-MH rechargeable batteries to fail due to deep discharge. The design uses a TP4056 charging/bms module (with a Type-C port) and 18650 Li-ion batteries (either one or two connected in parallel). Basic soldering skills are required. Any filament starting from PLA should be ok. I used white ASA with 0.08mm layer height, but 0.2 will do just fine.
