4 ESP32 projects that need nothing more than the board and a USB cable
You don't need extra sensors just to build a couple of ESP32 projects
Four ESP32 projects can be built using only the board and a USB cable. The first project is an ad blocker that uses an ESP32 with extra memory to maintain a blocklist and prevent content from showing up on your devices. The ESP32's ability to handle DNS lookup makes it suitable for this application. Another project is motion detection using ESPectre, which checks CSI records from Wi-Fi packets transmitted by a router to calculate a motion score.
Once calibrated, ESPectre's motion detection provisions are reliable. The third project is an uptime monitor powered by an ESP32, which keeps an eye on essential services and notifies you if they go offline. This can be done using ESPHome and Home Assistant. The last project is a Bluetooth proxy, which can accept signals from BLE devices and forward them to Home Assistant over Wi-Fi, either passively or actively.
The ESP32-C6 board can even use its 802.15.4 module for Zigbee projects or Thread-based smart home devices.
