CircuitPython 提供了一种和微控制器板进行交互的革命性方式。这篇文章介绍了如何使用 CircuitPython 来监测温室的温度、湿度以及环境光，并且使用 CircuitPython MQTT 客户端将结果发布到一个MQTT中介(broker)。你可以在若干个程序中订阅 MQTT 队列并进一步处理信息。

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on ...

The operating principles of our approach are closely related to those of magnetometers based on spin precession in atomic vapours. In particular, detecting the relative energy shift induced by a ...

Modern microcontrollers like the RP2040 and ESP32 are truly a marvels of engineering. For literal pocket change you can get a chip that’s got a multi-core processor running at hundreds of megahertz, ...

Adafruit have announced the availability of its new Triple-axis Magnetometer offering a sensor capable of sensing ranges from +-50 gauss (+- 5000 uTesla!) with no range-setting required. For high ...

Adafruit has this week announced the availability of a new Wide-Range Triple-axis magnetometer, reference MLX90393, priced at $9.95. The small devices capable of measuring invisible magnetic fields ...
