Frequently asked about this product
Is the I2C Barometric Pressure & Temperature Sensor (HP203N) compatible with Arduino, ESP32 and micro:bit?
Yes. The I2C Barometric Pressure & Temperature Sensor (HP203N) talks over a standard I2C/SPI/UART bus at 3.3 V or 5 V logic, so it connects directly to Arduino (UNO/Nano/ Mega), ESP32, ESP8266 and micro:bit boards. Example sketches for Arduino IDE, Mixly and Mind+ are included, and the bus address can be reconfigured when several modules share one bus.
What voltage does the I2C Barometric Pressure & Temperature Sensor (HP203N) run on?
The I2C Barometric Pressure & Temperature Sensor (HP203N) 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 I2C Barometric Pressure & Temperature Sensor (HP203N) good for?
The I2C Barometric Pressure & Temperature Sensor (HP203N) 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.
