3.3 V-powered pH and ORP probe interface using an ADS1115 module, MCP6002 through-hole buffers, and DS18B20 temperature sensing. External ESP32 connection is through one 5-pin header carrying 3V3, GND, SDA, SCL, and DQ; ADS1115 ADDR is fixed locally and ALERT is unused.

A compact battery-powered door/window sensor built around the ESP32-C3-MINI-1-N4 module. The design uses a single non-rechargeable AA cell with a TPS613221A 3.3 V boost regulator, reed switch magnetic contact sensing, low-power wake/report/sleep firmware strategy, RGB status LED for setup feedback, BOOT/EN controls, programming header, and input polarity protection. It is intended for smart-home security and automation applications, supporting WiFi or Bluetooth LE hub reporting with emphasis on low idle current, reliable RF burst power delivery, and field-replaceable battery operation. #ESP32-C3 #BLE #WiFi #DoorSensor #WindowSensor #ReedSwitch #LowPower #BatteryPowered #SmartHome #IoT
