Hi, friends! Please help me understand the humidity sensor SHT30-ARD. Sensirion does not have such a sensor or it is very old. Perhaps this is some kind of Chinese version. This sensor is not a SHT30-DIS (have't I2C) and not a SHT30-ARP (have't analog output). When power is applied to it, a short pulse passes to pin 1 and then a sequence of 5.4 seconds duration out to pin 4. What is it and how to decode it? |

For starters, what indication do you have that such a chip exists? :-// |

The connection is very similar to the SHT30-ARP, but it outputs a digital signal. Inscription: SHT30 ARD33P I can take a photo only tomorrow... |
