How to build a simple Meshtastic IoT sensor grid with the ThinkNode M1 & M2 devices.

Build a Digital Timer Switch that allows you to switch devices on or off on a specified schedule, e.g. your garden sprinkler or lights in your home. This Digital Timer Switch will always have accurate time since it synchronizes its clock with an internet time server. No need to adjust the clock for daylight savings time or to set it after a power outage. Furthermore, the large display makes it easy the set or change schedules.

Build a Parking Sensor with the TOF10120 IR Laser Distance Sensor and a CrowPanel 3.5" ESP32 Display. A parking sensor helps you to avoid obstacles while parking, for instance, by measuring the distance between your car and the garage wall. This Parking Sensor accurately measures the remaining distance and shows it in big, color-coded digits. It furthermore features a set button that allows you to set the warning distance.
