He used anRF52382 board for BLE, a DHT11 for humidity and temperature monitoring and a Raspberry Pi. It sounds like a lot of parts, and it is, but [Vaishali] managed to build this, an enclosure, and used Adafruit IO to monitor it all.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
