Digital humidity sensor for industrial applications goes global 

Joining Sensirion’s range of fourth-generation humidity sensors is the SHT4xI-Digital sensor platform, designed for challenging industrial applications. The series consists of two accuracy versions SHT40I and SHT41I, which offer 5V supply voltage and increased ESD protection.

SHT4xI-Digital is based on Sensirion’s proven CMOSens(R) technology which, says the company, ensures maximum reliability, as demonstrated by extensive accelerated lifetime tests such as 85 C/85 per cent RH for 1,000 hours. The sensor enables seamless integration with its wide operating voltage range, small size and robust housing. 

Based on its features and Sensirion’s advanced humidity sensing expertise, the SHT4xI-Digital is suitable for conducting measurements under harsh conditions in industrial application Sensirion’s CMOSens(R) technology provides a complete sensor system on a single chip, with a fully calibrated digital I2C fast mode plus interface. The sensor platform covers operating ranges from 0 to 100 per cent RH and from -40 degrees C to 125 degrees C with a supply voltage extending from 2.3 to 5.5V.

“The SHT4xI-Digital humidity and temperature sensor platform is our response to challenging industrial requirements. It enables reliable measurements in harsh and unfavourable environments,” said Maximilian Eichberger, director of product management humidity and temperature sensors at Sensirion. “The sensor platform’s robustness and extended supply voltage range allow long-term stability during operation in industrial applications. We are making a lasting contribution to our customers’ project-related success by drawing on our many years of humidity sensing expertise and optimizing our sensors to suit specific market conditions,” he said.

Headquartered in Stäfa, Switzerland, Sensirion AG is a leading manufacturer of digital microsensors and systems. Its product range includes gas and liquid flow sensors, differential pressure sensors and environmental sensors for the measurement of humidity and temperature, volatile organic compounds, carbon dioxide and particulate matter (PM2.5). 

An international network with sales offices in the USA, Europe, China, Taiwan, Japan and Korea supplies international customers with standard and custom sensor system solutions for a wide range of applications. Sensirion sensors are commonly used in the medical, industrial and automotive sectors, and in analytical instruments, consumer goods and HVAC products.
