Description

1. With metal shielding, strong anti-interference reserved CPU (STC15F104) position, can upgrade secondary development by itself
2. Two selectable differential inputs
3. On-chip low-noise programmable amplifier with an optional gain of 32, 64, 128
4. The on-chip voltage regulator circuit can directly provide power to external sensors and on-chip A/D converters
5. The on-chip clock oscillator does not require any external devices, and an external crystal oscillator or clock can also be used if necessary
6. Power-on automatic reset circuit
7. Simple digital control and serial communication: all controls are input by pins, and the registers on the chip do not need to be programmed
8. Selectable output data rate of 10Hz or 80Hz
9. Synchronously suppress 50Hz and 60Hz power interference
10. Power consumption (including regulated power supply circuit): typical operating current: <1.7mA, power-off current: <1 micro V
11. Working voltage range: 2.6~5.5V
12. Working temperature range: -20~+85 degrees Celsius
