Comimark Temperature Probes & Sensors Editorial Review

The Comimark 1Pcs SHT20 Temperature Humidity Sensor Modbus RS485 High Precision Transmitter has mixed reviews from customers. Some users were unable to get technical information on the product despite giving feedback. One user found the sensor to work well with a PLC but had trouble getting the modbus master to control the scan. Another user bought four units and found that two of them no longer read humidity while one returned incorrect temperature and humidity readings. There were issues with significant internal heat generation when powered by 24V, and powered with a switched fan the readings were useless. Two gotchas for usage were reported by one user; the unit must be power-cycled for address configurations to take effect, and there must be a wait after writing a configuration register before reading another. The lack of documentation was a significant issue for many users of the product.
