DHT11 / DHT22 Temperature and Humidity Sensor Module – Digital Sensor for Arduino and Microcontrollers
DHT11 / DHT22 Temperature and Humidity Sensor Module – Digital Sensor for Arduino and Microcontrollers
The DHT11 and DHT22 Temperature and Humidity Sensor Modules are highly popular digital sensors designed to measure ambient temperature and relative humidity with ease and accuracy. These modules are ideal for hobbyists, educators, and developers working with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms.
Both sensors offer digital signal output for simple and reliable data acquisition, with built-in analog-to-digital conversion and single-wire communication, making them efficient and easy to use in weather monitoring stations, smart home automation, HVAC systems, and IoT applications.
🔍 Sensor Variants:
DHT11 – Basic, cost-effective sensor with decent accuracy and limited range
DHT22 (also known as AM2302) – Higher accuracy and wider range, suitable for more demanding applications
📊 Key Specifications:
DHT11:
Temperature Range: 0°C to 50°C (±2°C accuracy)
Humidity Range: 20% to 90% RH (±5% accuracy)
Sampling Rate: Once every 1 second

How to Request a PCB Layout / Design
- Send your complete schematic or diagram via our Facebook page.
- Our team will review your diagram carefully to understand the design scope and requirements.
- A detailed quotation will be provided based on:
-
- Design complexity
- Board size and number of layers
- Components and package types
- Special routing or manufacturing requirements
📌 Providing your diagram is essential so we can give you an accurate and fair quotation.
PCB Layout & Design Requirements
To ensure quality and accuracy, please note the following:
- All schematics must be clear, complete, and properly labeled
- Specify:
- Board dimensions (if available)
- Number of PCB layers
- Preferred components or footprints (if any)
- Hand-drawn, unclear, or incomplete schematics are not accepted
- Rush or urgent requests may incur additional charges
What’s Included in the Design Package
Each completed project includes the following deliverables:
✅ 2D PCB layout images
✅ 3D PCB render images
✅ PCB Gerber files (ready for fabrication)
✅ Bill of Materials (BOM)
✅ Component Placement List (CPL / Pick-and-Place file)
