20191209· The MPU9250 is a 9axis MEMS sensor from InvenSense®. It’s Arduino compatible, making motiontracking measurements simple. Compatibility aside, it’s a high performing device with low power consumption and a significantly smaller form factor as compared to its previous successor MPU9150. In today’s blog, I’ll be helping you get started with the MPU9250, alongside how to hook it up ...
20180216· Features of the MQ sensors . Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
