Digital temperature & humidity sensor LED 3-pin DHT11 PCB for Arduino

Smart 3pin DHT-11 DHT11 Digital Temperature and Relative Humidity Sensor Module + PCB for Arduino DIY Starter Kit

Product Introduction

HW-036 is a digital temperature and humidity sensor, with the DHT11 sensor as its core component. The sensor contains a resistive humidity sensing element and an NTC temperature measurement element, connected to a high-performance 8-bit microcontroller. It can detect the temperature and humidity around the sensor and output this information in the form of digital signals from the S-pin.

Product Parameters:

1. Supply voltage: DC 3.3–5.5 V

2. Output: Single-bus digital signal

3. Measurement range: Humidity 20–90% RH, temperature 0–50℃

4. Measurement accuracy: Humidity ± 5% RH, temperature ± 2℃

5. Resolution: Humidity 1% RH, temperature 1℃

6. Interface description: VCC: Power supply positive pole

GND: Power supply negative pole

DATA: Microcontroller IO port

When using, be sure not to connect the positive and negative poles of the power supply in reverse to avoid damaging the sensor

Do not connect VCC and GND in reverse.

Application Scope:

This module can be applied to items such as HVAC, air conditioning, test and inspection equipment, automobiles, automatic control, humidity regulators, dehumidifiers, etc.
