Review on ๐ŸŒก๏ธ Uxcell Pressure Temperature Breakout Humidity Test Kit: Accurate Measure & Inspect for Enhanced Analysis by Will Rahman

Revainrating 1 out of 5

This is LM75BD temperature only, no pressure, no humidity - description is inaccurate

I was very happy to get a device that measures 3 environmental conditions in one package can. When the product arrived I discovered that it's just an LM75BD sensor, which only supports temperature monitoring and a watchdog timer (where it can signal when the temperature rises above a set point). In addition, the device does not correspond to the passport and the temperature is not saved in the format described in the documentation. Instead of fractional degrees (e.g. a resolution of 0.125 ยฐC is supported for LM75D and a resolution of 0.5 ยฐC for LM75a) an integer number of degrees is returned. C with a resolution of 1 degree. C. Conclusion - the description is wrong - only the temperature can be measured, and the resolution of the product is much lower than that described in the datasheet for chips with the same mark.

Pros
  • LM75A, precision sensor soldered to PCB, I2C and SPI interface
Cons
  • Very expensive
