To make selecting a Digital Sensor Module easier, we've created a Sensor Module Product Guide that allows you to easily compare key product characteristics.
All HopeRF modules are supplied 'as is' as components for inclusion in your own products. As such, we make no warranty as to whether they are fit for purpose for any specific application. Customers should seek professional advice in relation to issues such as EMC compliance, electrical safety, etc, depending on the applications to which they intend applying these components.
If you need further advice, please contact us before selecting any HopeRF product.
HopeRF's digital Relative Humidity (RH) and temperature sensors incorporate monolithic CMOS ICs that integrate temperature and humidity sensor elements, analoueg-to-digital converters, signal processors, calibration data and an I2C interface.
HopeRF's patented use of industry-standard, low-K polymeric dielectrics for sensing humidity enables lower cost while ensuring high accuracy and long-term reliability. Both the temperature and humidity sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory, ensuring that the sensors are fully interchangeable, with no re-calibration or software changes required.
HopeRF's 24-bit barometric sensors employ MEMS pressure sensors with an I2C interface to provide accurate temperature, pressure or altitude data. The pressure and temperature outputs are digitised by a high resolution 24-bit ADC, with the altitude calculated by a patented algorithm based on the pressure and temperature data; with processing done on-board to save the need for external MCU processing. Pressure can be resolved to fractions of a Pascal, with altitude accurate to 0.01 meter.
