By detecting body heat, these modules sense when people are moving. Connect them to your development board to integrate them into alarm systems, automated lighting, and other applications.

Modules with an adjustable infrared motion sensor let you expand or lower the sensing distance. To connect them to a device, solder wires or headers to them.

Modules with a fixed infrared motion and thermal sensor can detect if a person is moving or even just present within the sensing distance. That means you could use them to automate lighting in an office where workers are sitting still. To connect them to your device, solder on wires or headers. For a solderless connection, use a Qwiic cord.

Program mini development boards and other custom circuit boards with these modules. To program your board, attach the module and connect it to your computer using a USB cord (sold separately). Then transfer the code from your computer to the development board. Once the board has been programmed, the module can be removed. Choose an operating voltage that supports the board you’re programming.

Keep equipment running and working conditions safe—these modules add air quality tracker capabilities to your development board. Each module gathers data on air conditions, ranging from temperature and humidity to carbon dioxide or volatile organic compound (VOC) levels. These modules easily connect to boards and other components with Qwiic cords or by soldering.

Modules with an air quality sensor identify spikes in VOC levels to track air quality changes. Instead of directly measuring VOCs, they measure how much the VOC level has changed in the last 24 hours.

Modules with a temperature, humidity, and air quality sensor help you make sure the air is healthy in your facility. They directly measure the amount of carbon dioxide in the air.

Modules with a temperature, humidity, and barometer sensor are often used as part of an automated system that runs equipment based on the weather. For instance, you can use them in a system that will turn on a humidifier if humidity dips below a certain level.

Modules with a temperature, humidity, air quality, and barometer sensor give you the most comprehensive picture of air conditions in your facility. They directly measure the amount of VOCs and give you an estimated measurement of carbon dioxide based on VOC levels. They monitor air quality using Germany’s Air Quality Index (AQI).

Position these modules in vents or near sensitive electronics to monitor airflow. Unlike handheld meters, these modules continuously monitor airflow and alert you to changes. Connect them to development boards with Qwiic cords or by soldering.

Measure your device's acceleration, rotation, or orientation. These modules gather data over time and track movement, which can help improve performance, debug issues, and calibrate your components. Solder them onto a development board. To connect them to your device, solder on a wire or header. For a solderless connection, use a Qwiic cord (not included).

An accelerometer measures the rate at which your device is speeding up or slowing down. A gyroscope measures how fast your device is rotating. A magnetometer measures your device's orientation.

Safely power low-voltage components in circuits with a high-voltage source. These regulators turn high-voltage inputs into lower, more stable outputs.

Regulators with an adjustable output voltage let you fine-tune the output to best fit your circuit. To adjust the output voltage, connect them to two resistors (not included). The resistance values determine your output voltage.

Dropout voltage is the minimum required difference between the input voltage and your regulator’s output voltage.

Measure your equipment’s pressure and send the data directly to a development board or single-board computer. Also known as transducers, these transmitters convert pressure into an electrical I2C signal and transmit it to your board by connecting a cord (not included) with a Qwiic connection. Transmitters connect directly to your machinery via tubing (not included), letting you monitor activity such as gas tank pressurization and liquid fill level.

Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature. They will only provide accurate readings within the rated pressure range.
