Digital Thermometer / Hygrometer Sensor (DHT11) for Arduino
Looking to add environmental monitoring to your Arduino? This digital thermometer / humidity sensor gives you a wealth of information from a tiny package!
Measure temperature from 0°C to 50°C (32°F to 122°F) with an accuracy of 1°C! Measure relative humidity from 20 to 90%RH with an accuracy of 4%RH!
This module sends out pure digital data using just one signal line to both receive the trigger signal and send the serial data.
The digital design allows this sensor to operate on negligible power, waking up for a short burst of activity only when requested!
This sensor is ready to be soldered into a standard protoboard or wired into a breadboard using the 4 x 0.1" pins on the bottom of the unit. It has simple voltage requirements (3VDC - 5.5VDC) and sends data to the Arduino in an easy to read format.
We stock 2 versions of this sensor, based on availability from 2 different manufacturers. The other version is special board-mounted variety of this part (not pictured), which consists of a DHT11 sensor mounted to a small breakout board that includes a 10K pull-up resistor on the data line, and breaks out the GROUND, POSITIVE_POWER, and SERIAL_DATA connections to three sturdy, breadboard-friendly 0.1-inch-pitch header pins (header pin 1 is ground, header pin 2 is positive power, and header pin 3 is serial data) - We consider this version easier to use since it includes a header and a pull-up resistor. If you place an order for this product (VUPN5921), we reserve the option to send you either the standard or the board-mounted variety. If you have a preference for one or the other, please specify in the comments field during checkout and we will try our best to accomidate you.
- Pin 1: VDD (3VDC - 5.5VDC)
- Pin 2: Serial Data
- Pin 3: not connected
- Pin 4: GND
