Description

Manufactured by Hope Microelectronics, the HP203B is a high-precision barometer and altimeter that measures the pressure and the temperature by an internal 24-bit ADC and compensates using a patented algorithm.

The pressure and temperature outputs are digitized by a high resolution 24-bit ADC. Typical active supply current is 5.3 uA per measurement per second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with output in fractions of a Pascal, and altitude can be resolved in 0.01 meter resolution. The HP203B is specified for operation from -40°C to +85°C.

Applications of HP203B include:

  • Mobile altimeter / barometer,
  • Industrial pressure and temperature sensor system,
  • Panel computer and weather station equipment, etc.

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All mini modules are 50.8 x 31.75 mm.
