The Seven Sensors and Breakout Boards to Avoid in a Product
The article discusses seven sensors and breakout boards that should be avoided in product development due to various issues such as questionable accuracy, proprietary protocols, and safety concerns. These sensors include the DHT11 and DHT22 temperature-humidity sensors, the HC-SR04 ultrasonic distance sensor, and the ACS712 current sensor, among others. The article provides alternative options for each of these sensors, highlighting the importance of selecting reliable and safe components for product development.
- ▪The DHT11 and DHT22 temperature-humidity sensors have questionable accuracy and proprietary protocols, making them unsuitable for product development.
- ▪The HC-SR04 ultrasonic distance sensor lacks temperature compensation and is not suitable for use outside a temperature-controlled room.
- ▪The ACS712 current sensor breakout boards pose safety concerns due to inadequate consideration of mains power safety, such as creepage distance and separation.

The Seven Sensors And Breakout Boards To Avoid In A Product No comments by: Maya Posch August 2, 2026 Title: Copy Short Link: Copy We’ve all seen these sensors and modules kicking around, as part of beginner kits, strapped into prototypes and potentially even in products deployed in the field. Yet as [John Teel] rightfully points out in a recent video, most of these have no business ever being used in a real product, and might not even be suitable for prototyping. First up is a combination of the related DHT11 and DHT22 temperature-humidity sensors. As common as these are, they’re also pretty sketchy with their proprietary one-wire protocol and at most questionable accuracy, worsened by not having a good supply chain.
