Description

The HS-S26P module integrates a DHT11 sensor, which combines a capacitive humidity sensing element and an NTC thermistor. This pairing enables the measurement of both relative humidity and ambient temperature. The sensor’s internal 8-bit microcontroller handles signal conditioning and provides a calibrated digital output via a single-wire serial interface, simplifying data acquisition.

Designed for reliability in standard indoor environments, the module offers a practical balance of performance and cost for hobbyist projects, educational setups, and basic home automation systems. Its straightforward digital protocol eliminates the need for analog-to-digital conversion on the host microcontroller.

Key Features

  • Digital Single-Bus Output: Provides pre-calibrated digital readings for temperature and humidity, simplifying code development and reducing host MCU overhead.
  • Wide Voltage Compatibility: Operates from 3.3V to 5.5V DC, ensuring direct compatibility with 5V Arduino boards and 3.3V Raspberry Pi/ESP platforms.
  • Optimized Power Profile: Low current draw during measurement cycles supports long-term operation in battery-powered data loggers and wireless sensor nodes.
  • Compact PCB Construction: The module features a standard 35mm x 40mm footprint with a mounted DHT11 sensor and a clear silkscreen for easy pin identification.
  • Fast Sampling Capability: Delivers a new reading every 2 seconds, providing adequate response time for most environmental monitoring applications.

Applications

  • Indoor climate monitoring and data logging for home automation systems.
  • Environmental condition tracking in DIY weather stations and Grow boxes.
  • Basic HVAC and fan control triggers in Arduino or Raspberry Pi projects.
  • Educational demonstrations of digital sensor interfacing and IoT principles.

Frequently Asked Questions

What is the operating voltage range for the HS-S26P DHT11 module?

The HS-S26P module operates from 3.3V to 5.5V DC. This wide range allows direct connection to the 5V pin of an Arduino Uno or the 3.3V pin of a Raspberry Pi or ESP32 without requiring a logic level converter.

How do I wire and read data from this sensor with an Arduino?

Connect the module's VCC pin to Arduino 5V, GND to GND, and the DATA pin to any digital I/O pin (e.g., pin 2). Use a 4.7kΩ to 10kΩ pull-up resistor between the DATA pin and VCC. You can then use the popular DHT-sensor-library to easily read temperature and humidity values in your sketch.

What is the measurement accuracy and sampling rate of the DHT11 on this module?

The integrated DHT11 sensor provides temperature readings from 0°C to 50°C with an accuracy of ±2°C, and humidity readings from 20% to 90% RH with an accuracy of ±5% RH. A new reading is available every 2 seconds; polling the sensor more frequently will return the last measured value.
