SparkFun has launched a pair of recent Qwiic-based breakout boards for Texas Devices’ TMAG5273 linear Corridor-effect sensor — providing a low energy draw and excessive accuracy for magnetic discipline sensing throughout three dimensions.
“The SparkFun TMAG5273 Qwiic Linear 3D Corridor-Impact Sensor is a low-power, high-precision magnetic discipline sensor that may detect a magnetic discipline’s presence, power, and route in three dimensions,” explains SparkFun’s Chris McCarty of the brand new sensor board. “This board is ideal for purposes involving magnetic proximity detection, door and window sensing, cellular rotor and management, and extra, all on a Normal 1x1in. Qwiic breakout!”

The Texas Devices TMAG5273 sensor on the coronary heart of the board provides a claimed ±40mT vary at an 820LSB/mT sensitivity, or a wider ±80mT vary at 410LSB/mT sensitivity, with a rotational accuracy good to ±0.5 levels per 360-degree rotation and a 5 per cent magnetic drift.
Mounted on a breakout with two solderless Qwiic connectors — although with the essential pins introduced out to a breadboard-friendly 0.1″ pin header too — the sensor communicates with a number microcontroller over I2C, drawing simply 2.3mA of present whereas actively sensing dropping to 1µA in sleep mode. Ought to the sensor should be disabled, there is a button proper on the board — and a pin on the 0.1″ header for a similar objective.

If the full-size breakout is just too cumbersome, in the meantime, SparkFun has additionally introduced a miniaturized model — with all the identical options of the full-size variant, however on a half-size 0.5×1in. board. The largest distinction, bar the dimensions: the 2 Qwiic connectors are hidden across the again of the board at a 90 diploma angle, to scale back the wired footprint nonetheless additional.
Each boards can be found on the SparkFun retailer now priced at $6.50 for the SparkFun Mini Linear 3D Corridor-Impact Sensor and $5.95 for the full-size SparkFun Linear 3D Corridor-Impact Sensor, each earlier than quantity reductions. Orders positioned earlier than December twenty fourth can use the promo code “holidays2023” to obtain a free Qwiic MultiStar Constellation Decoration.
