This MKR WAN 1300-powered rover was impressed by the orb-weaver spider

Orb-weaver spiders are sometimes present in gardens and are well-known for the intricate webs they spin to catch pre, and because the title implies, this net is within the form of a circle. In step with the theme, element14 person Miloš Rašic had the thought to construct a small rover taking inspiration from the orb-weaver spider and NASA’s newest rovers in that it “casts” a internet of small sensor bins inside a round space that every report information to a central receiver, and it might accomplish that autonomously.

For now, Rašic needed to stay with measuring air high quality, so he started by putting a MKR WAN 1300 into his first “sensor field” that may act as a transmitter to ship the information to the receiver by way of LoRaWAN. From right here, he included a DHT22 for temperature/humidity, a BMP280 for air strain, a QYF-919 real-time clock module, and an HL-83 rain sensor. A pair of AA batteries offered energy to the whole lot.

The receiver, or “floor management station,” consisted of one other MKR WAN 1300 board, an LCD, a buzzer, and a battery degree module. Aside from the sensor bins, the rover proved to be probably the most difficult to implement, however on the finish Rašic was capable of get it working completely.
