PTH Fusion Sensor suits weather station applications.

Press Release Summary:

Housed in 5 x 3 x 1 mm² QFN package, Model MS8607-02BA01 utilizes piezoresistive sensor to measure pressure and temperature, and capacitive-type sensor for relative humidity. Unit converts uncompensated analog output voltages to 24-bit digital value for pressure and temperature measurements, and 12-bit digital value for RH. Using I²C communication and operating from 1.8–3.6 V, sensor features pressure range of 10–2,000 mBar, temperature range of -40 to +85°C, and humidity range of 0–100% RH.

Original Press Release:

MS8607-02BA01 PTH Fusion Sensor


Measurement Specialties, Inc. (NASDAQ: MEAS) has just released to production its MS8607-02BA01 digital PTH (Pressure, Temperature, Humidity) fusion sensor. This small QFN packaged 5 x 3 x 1mm³ integrated pressure, humidity and temperature sensor is ideal for weather station applications embedded into compact devices, or any application in which pressure, humidity and temperature monitoring is required.

The MS8607-02BA01 includes two sensors with distinctive MEMS technologies to measure pressure, humidity and temperature. The first sensor is a piezoresistive sensor providing pressure and temperature, and the second is a capacitive-type sensor providing relative humidity. Each sensor is interfaced to a ΔΣ ADC integrated circuit for digital conversion where the MS8607-02BA01 converts the uncompensated analog output voltages to a 24-bit digital value for the pressure and temperature measurements, and a 12-bit digital value for the relative humidity measurement.

This sensor requires 8 pads for operation, uses I²C communication and operates at a 1.8 – 3.6V supply voltage. With an operating pressure range of 10 to 2000mBar, it has a pressure accuracy of ±2.0mBar (@25°C, 300…1200mBar) and pressure resolution of 0.016mBar. Operating at a humidity range of 0 – 100% R.H., it has a humidity accuracy of ±3.0% R.H. (@25°C, 20…80% R.H.) and humidity resolution of 0.04% R.H. In regards to temperature, this sensor operates at -40°C to +85°C with a temperature accuracy of ±2.0°C (-20°C…+85°C) and temperature resolution of 0.01°C.

The MS8607-02BA01 is well suited for applications in the consumer electronic and industrial marketplace such as smartphones and tablet PCs, HVAC applications, weather stations, printers, and home appliance and humidifiers.
