LinPicco™ Capacitive Humidity Module from IST

With calibrated and linearized analog output signal

Innovative Sensor Technology: The LinPicco series provides a Plug&Play module for humidity and temperature measurements. The module is fully calibrated, has an analogue output signal and is temperature compensated. Additionally, no extra software is needed. The principle of the module is a capacitive change which is transformed in to an electrical signal. The signal is being processed by an integrated component and afterwards put out as an analogue output. The analogue LinPicco module is suitable for applications where fast, simple and easy to integrate humidity and temperature measurement is needed.

The following list showcases the advantages the LinPicco has. It is not a list of the modules full range of capabilities and should not be seen as such.

•  Precise humidity measurement
• Very low drift due to wide sensor variation
• Fully calibrated
• Module with external sensor available
• Easy to integrate
• PCB moisture protected
• Various analog output signals
• Customer specific module available upon request

Among other, the LinPicco humidity module is suitable for, but not limited to, the following application areas:

• HVAC
• Home appliances and white goods
• Monitoring
• Process and automation

The LinPicco module contains the Innovative Sensor Technology IST AG P14 capacitive humidity sensor. The P14 capacitive RH sensor on the LinPicco consists of a ceramic substrate on which a thin film of polymer is deposited between two conductive electrodes. The sensing surface is coated with a microporous metal electrode, allowing the polymer to absorb moisture while protecting it from contamination and exposure to condensation. As the polymer absorbs water, the dielectric constant changes incrementally and is nearly directly proportional to the relative humidity of the surrounding environment. Thus, by monitoring the change in capacitance, relative humidity can be derived. The LinPicco humidity module is available with three output signals, A420 (4mA to 20 mA), A01 (0V to 1 V) and A05 (0 V to 5V).
