Esp32-c3-iot sensor board
Esp32-c3-iot sensor board is an open source ESP32 PCB design by Ans1S: a 4-layer, 35.4 × 21.6 mm board with 57 components (32 distinct parts). It is built around the SOFNG MC-311D, ESP32-C3, TP4056-42-ESOP8, SKCL3130ME and more. Filed under sensors and power & battery and iot & wireless.
Open-source ESP32-C3 platform for ultra-low-power environmental sensor networks powered by recycled LiPo cells. Includes KiCad PCB, PlatformIO firmware (ESP-NOW + ThingSpeak), BME280/BME680 support, deep-sleep optimizations and measured >12 months runtime on typical cells.
Disposable vapes are designed for a very short life. The rechargeable lithium cell inside them often is not. W-Charger turns suitable recovered cells into the power source for compact wireless sensor nodes — then makes the whole network easy to see, configure and update from one station.
Many disposable vapes end up in household bins or as litter. That throws away valuable materials, creates a fire risk in waste handling, and can release harmful substances when a damaged cell reaches the environment. At the same time, the product enclosure gives its rechargeable cell no practical second life…
