As of CircuitPython 7.0.0, pulseio is Adafruit Python DHT Sensor Library. all systems operational. My DHT11 sensor comes on a board with a +, -, and out wires and I have a raspberry pi B+ I put the plus into a power pin (1), the minus into a ground pin (6), and the out . Now create an instance of either the DHT11 or DHT22 class, depending on the type of sensor you're using (for the AM2302 sensor use the DHT22 class). "To achieve great things, two things are needed: a plan and not quite enough time", This library uses the pulseio module in CircuitPython. circuitpython-build-tools package. If a photo ID is provided within 60 days, a provisional card will convert to a full MCPL Access Pass.
