This is a custom 2m probe version designed for users who require a longer probe section; please use this version (the default version is 1m in length).

We would like to share a new temperature and humidity sensor that is different from most of these sensors (wireless, with display) in that it only has the probe with wires and the need for USB power. What we hope to say is that on top of this sensor, it has the flexibility to capture some specific temperature and humidity data in real time, for example you can put the probe into a refrigerator (it's waterproof and resistant to low temperatures) to capture the temperature inside the refrigerator. Or you can put it under the bed sheet to collect the problem of the bed. Or put it in a pet's nest to see what the environment is like inside. We tested it for quite a long time and determined that the sensor performed well. There is a slight lag for high humidity measurements as the probe needs to be sealed for processing. A Swiss SHT40 chip is used in the sensor, so feel free to come along and explore its possibilities.
