In view of the very weak temperature sensor signal, high-precision, low-noise operational amplifiers and high-precision, low-power ADCs are needed. Operational amplifiers are available for selection: MS8551 or MS8601, which has the advantages of low offset (1uV), low noise (22nV√Hz), small package, etc. It has an absolute advantage among domestic brands.
ADC is available: MS1112 or MS1100, with high precision (16bit), multi-channel, low power consumption (<1uA), IIC interface, internally integrated 2.048V reference source, small package, etc.
MCUs are available: MS616F512, built-in LCD, 16-bit single-chip microcomputer, low power consumption, built-in low-voltage detection, minimum working (1.8V) and other advantages;
The temperature measurement program uses a full set of Ruimeng products, the application is more stable and the collocation is more reliable.
