4pcs Door Sensor Magnetic Switch for Arduino, ESP32, ESP8266, Raspberry Pi

The 4pcs Door Sensor Magnetic Switch set has garnered mixed feedback from customers who have implemented it into their DIY electronics projects, specifically with platforms like Arduino, ESP32, and ESP8266. Users have noted that these sensors tend to perform well in scenarios involving home security and automation setups. They have reported positive experiences with the sensors' sensitivity and functionality, indicating that the input response changes effectively when the magnet is moved away from the switch. However, not all reviews have been as favorable. A significant concern raised by some users is the inConsistency in the quality of the sensors, with reports that about half of the devices in a package may fail to open correctly after the magnet is removed, leading some to label these as "junk." Additionally, while the adhesive backing is convenient, it's viewed as subpar by at least one customer who opted for higher-quality alternatives. Users noted that while there are no mounting screws included, the necessary holes for screws are present, which suggests valuable foresight in the design. In summary, the product offers a promising solution for those engaging in custom electronics projects, particularly for security applications, but potential buyers should be aware of varying sensor reliability and may need to make adjustments in terms of mounting methods. **
