This module allows you to measure environmental parameters of temperature and humidity using the DHT11 sensor. Additionally, based on the sensor readings LEDs will turn on to display temperature scale ...

I’ve tried the DHT11 sensor modules at both Vcc 3.3V and 5.0V, and at both voltages the humidity values are bad. dfrobot has introduced a V2 DHT11 sensor module that changes the 10K pull-up to 4.7K.

Thus, the car adds a DHT11 temperature and humidity sensor, along with a BMP280 air pressure sensor using the Grove connectors. Driving the car is done via a Blynk smartphone app that communicates ...
