Handheld Readout Device(HRD) for Sensors

Readout Device for all I2C Sensors

Similar projects worth following
Recycling of material that would otherwise end up in the waste stream.

HRD for Sensors is the quick solution to quality check
I2C Interface-Sensors with 16-bit commands.

Set measurement commands for data acquisition
and readout the measurements results.

For that purpose the handheld device must be wired to the Sensor
via its I2C interface.

Tested Firmware Version for SENSIRION SHT3X-DIS

Sensor probing requests.

0x44 Address "SHT3X-DFLT"

0x45 Address "SHT3X-ALT"

Power management for the LC-Display.

Display will be scrolled (11 digits).

HRD can be connected to external devices like personal computers to transfer and store the extracted technical data.

    Did first test for Vishay "VCNL4040"  Fully Integrated Proximity and Ambient Light Sensor with Infrared Emitter comibined with Sensirion "SCD30"  CO2, humidity, and temperature sensor.

  • power and energy-efficiency features

    Peter Loës04/07/2022 at 08:29 0 comments

    To achieve its power and energy-efficiency features, EFM32 products utilize ultralow active and idle power, fast wakeup and processing times, and most important, the ability to intelligently interact with peripherals and sensors autonomously without waking up the CPU and consuming more power.

    C is the Greenest Programming Language.
