Description

The Grove DHT11 module incorporates a capacitive humidity sensing element and a thermistor for temperature measurement. The sensor digitizes the analog signals internally, providing a calibrated digital output over a single data line, which reduces noise susceptibility and supports cable runs over 20 meters. It is factory calibrated, offering reliable performance for non-condensing environments.

Designed for general-purpose monitoring, the module performs optimally within 0°C to 50°C and 20% to 90% RH. Its compact form factor and Grove standardized connector make it ideal for rapid prototyping, educational projects, and basic environmental monitoring systems without requiring external signal conditioning.

Key Features

Combined digital temperature and humidity sensor in a single module
High-reliability capacitive humidity sensing element
Long-term stability and consistent measurement performance
Low-power operation suitable for battery-powered devices

Frequently Asked Questions

What is the operating voltage range for the Grove DHT11 sensor?

The module is designed to operate from a 3.3V to 5V DC power supply. It is compatible with most microcontroller development boards like Arduino (5V) and Raspberry Pi (3.3V) without requiring a level shifter for the data line.

How do I communicate with this sensor, and what is the output signal?

The DHT11 uses a single-wire digital communication protocol. You connect the data pin to a digital I/O pin on your microcontroller and use a dedicated library (e.g., DHT-sensor-library for Arduino) to request and read the pre-calibrated digital temperature and humidity values.

What are the optimal environmental conditions for reliable measurements?

For highest accuracy, use the sensor within 0°C to 50°C and 20% to 90% relative humidity. While it can measure from -20°C to 60°C and 5% to 95% RH, performance is specified and most stable within the recommended central range.
