Take the advantage of ready to use module with SHT30 sensor

The SHTxx sensors measure relative humidity and temperature of their direct environment. But what to do if PCB doesn’t allow the sensor to be placed in the optimal position?
This is an archive article published 03/07/2019. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Sensirion’s Design Guide Humidity Sensors describes how to design PCB, enclosure and place sensor to optimal location but in practice, there are also applications where it is not possible.

With the SCC30-DB module, designer can place a humidity and temperature sensor anywhere within a device and connect it to the main PCB with four wires. You do not need to spend time to create your own sensor module. Based on Sensirion’s experience and expertise, the SCC30 is optimized for easy design-in and sensing performance.

The SCC30 uses the latest generation sensor -SHT30. Module uses Scondar SCT2001WR-S-4P connector (compatible to JST part no. S4B-PH-SM4-TB). To support the development, we offer you mating connector, JST PHR-4 housing and pre-crimped wires.

The SCC30-DB supports I2C normal (100 kHz) and fast (400 kHz) mode. Lower frequencies (below 100 kHz) are recommended for communication because of capacitive coupling of cables with the I2C bus.

Sensirion Control Center

The most convenient way to evaluate SCC30-DB performance is the use of SEK-SHTxx/SGP30 evaluation kit. SEK-SCC30-DB, SCC30-DB module with cable for connecting to kit and Sensirion Control Center software. Software is available for Windows, Linux and macOS.

Control Center allows:
● Displaying the chart with the measured values from all connected sensors.
● Logging measured values to file with format compatible with Microsoft Excel.
● Renaming displayed sensor name, setting sample rate and configuring logging (every sample to every 1000th sample).
● Setting power supply voltage and I2C clock frequency for sensor connected to SEK sensor bridge
● Configuring sensor or running action in dependency of connected sensor

    • Set auto cleaning interval for SPS30 or manually run cleaning procedure
    • Turn on automatic self-calibration (ASC), set temperature offset or run forced re-calibration (FRC) for SCD30
    • Add absolute humidity and dew point plot, set ART (accelerated response time) mode, repeatability (measurement duration), turn on heater for sensor testing and set temperature and humidity alert limits for SCC30

Control Center looks and works well, look at it in the image gallery.
