Environmental sensors measuring temperature, relative humidity, and pressure as well as audible noise are usually supplied by a 24V DC rail in a factory automation environment. These sensors often use an IO-Link communication protocol to output data in digital format.

We have a broad range of environmental sensors for industrial applications, including MEMS pressure, humidity and temperature sensors, as well as microphones all providing small size, repeatability, reliability and low power consumption, enabling compact and cost-effective wired and wireless industrial sensor networks.

In addition, we have a range of STM8 and STM32 microcontrollers, DC-DC switching and linear voltage regulators and high-precision operational amplifiers.
