The BMHB9001 is a development board for Holtek Ultra-Low Voltage R to F Flash MCU BH67F2132. It is designed and produced by Best Health Electronics Inc.
The BH67F2132 has integrated two sets of independent measurement resistance/frequency (R/F) conversion circuits which do not require any voltage step-up components. The use of Flash type memory allows for increased flexibility during product development while its integrated true EEPROM memory can be used to store calibration data, thus greatly reducing production time and cost.

Our practical operation steps for temperature measurement are as below:
Connect to 1.1V to 2.2V power.
It takes about 0.5 seconds for warming up.
Users can start measuring when the LCD displays "Lo".
Put the finger on the sensor to measure temperature. It needs to take some time in this step.
The buzzer beeps when the measurement has been done.
It enters sleep mode after pressing the button. Users can press the button to wake up the board.
The LCD displays the last recorded temperature.
When the LCD displays Lo (as the step 4), users can start measuring again.
