Manometer click

Manometer click carries a piezoresistive silicon pressure sensor, the HSCMAND060PA3A3 from Honeywell, an industry-leading module with an extremely high accuracy of ±0.25%FSS BFSL. The click is designed to run on a 3.3V power supply. It communicates with the target MCU over I2C interface.

HSCMAND060PA3A3 features

The HSCMAND060PA3A3 has an industry-leading, extremely high accuracy of ±0.25%FSS BFSL. An absolute pressure range from 0 to 60 PSI makes it suitable for a variety applications. Beyond the measurement range, the sensor has a high burst pressure threshold, resulting in increased reliability.

Features and usage notes

The sensor on Manometer click is a highly reliable and robust unit. It's also fairly easy to use and implement. It requires no calibration and it compensates for environmental conditions by relying on its internal temperature sensor.

The HSC Series is calibrated over the temperature range of 0 °C to 50 °C (32 °F to 122 °F).

The temperature sensor can also be accessed independently through the I2C interface.

The barbed port accepts 4.93 mm (0.19”) tubing which connects directly (no special extensions required).

Code snippet

The following code snippet shows how our library simplifies the usage of Manometer click.

 1 #include "manometer_hw.h"
2 void main()
3 {
4     float pressure, temp;
5     int count = 0;
6     TWI_Init( 100000 );
7     manometer_init( MANOMETER_ADDRESS_TYPE_3, 0, 60 );
8     pressure = manometer_get_pressure();
9     temp = manometer_get_temp( CELSIUS );
10     if( pressure > 45 && temp > 35 )
11         count++;
12 }
