Key features
- Analog output from the classic National Semiconductor LM35 linear temperature sensor.
- LM35D range 0-100 °C with 10 mV/°C sensitivity; output voltage is directly proportional to temperature.
- Semiconductor sensors offer simple application, good linearity and high sensitivity for measurements below 100-200 °C.
- Pairs with Arduino sensor shields for effortless ambient-temperature interaction; new revision changes module size only.
Frequently asked about this product
How do I connect the LM35 Temperature Sensor to my controller board?
The LM35 Temperature 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 LM35 Temperature Sensor run on?
The LM35 Temperature 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 LM35 Temperature Sensor good for?
The LM35 Temperature 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.
