Frequently asked about this product
How do I connect the DHT11 Temperature & Humidity Sensor to my controller board?
The DHT11 Temperature & Humidity Sensor uses the standard 3-pin GVS (Ground-VCC-Signal) interface with an XH2.54 connector, so it plugs straight into Arduino UNO, ESP32, micro:bit and our sensor shields with a regular sensor cable — no soldering required. It works with Arduino IDE, Mixly, Mind+, Scratch and mBlock.
What voltage does the DHT11 Temperature & Humidity Sensor run on?
The DHT11 Temperature & Humidity Sensor runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the DHT11 Temperature & Humidity Sensor good for?
The DHT11 Temperature & Humidity Sensor is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
