Crowtail - DHT11 Temperature & Humidity Sensor (Grove Compatible)

This new Crowtail module (Grove compatible) can simplify the connections in your project and make your life easier! Say goodbye to messy wiring and incorrect pin connections, as the Crowtail module features a standard pin arrangement and can only be plugged in one way.

This module is based on the DHT11, the most common temperature and humidity sensor used with Arduino and Raspberry Pi. It's highly favored by hardware enthusiasts for its numerous advantages. For instance, it boasts low power consumption and excellent long-term stability. Despite its low cost, it delivers relatively high measurement accuracy. The single-bus digital signal is output through the built-in ADC, saving the control board's I/O resources.

You can use Crowtail modules with any microcontroller or HAT that comes with a Grove port. For example:

• Maker UNO RP2040
• Maker Pi Pico
• Maker Pi RP2040
• EDU:BIT
• EDU PICO
• Grove Base Shield V2
