Humidity & Temperature Transmitter The transmitter measures the humidity by the use of a capacitive sensing element and the temperature with an NTC thermistor. The microprocessor samples the humidity and temperature once per second. It calculates an averaging ** over a preset number of seconds and generates an output ** based on lower and upper ** range values. Standard range is 0…** rH, -40…60°C (-40…140°F) and 10 seconds average. The ** range of the temperature measurement and the averaging samples may be customized. Minimum and Maximum Values: Using the programming tool, the user has the option to read out and reset minimum and maximum values. The minimum and maximum values may as well be used as output **s. The minimum and maximum values are saved into the EEPROM and are available after a power interruption.
