DHT11 can be … WebJul 3, 2024 · 1 Answer. You require a pullup resistor between the data wire and VCC because the DHT11 uses a bidirectional communication system on a single wire. When neither end is communicating both ends of the link will be in "high impedance" mode - i.e., input mode. In that case the signal will be "floating" and needs the pullup to keep it in a … WebApr 24, 2024 · The sensor which is visible as a cable actually is a transistor-type component, enclosed into a metal covering. More information about the device is in its datasheet, so refer to it. Its working is similar to the DHT11 or DHT22 temperature and humidity sensor, which I have already completed in this series. grammar and beyond level 3 answer key
