The main chip of this module is CS1237.
This chip integrates "amplifier" and "ADC", which amplifies the differential signal of the sensor and turns it into a digital signal.
It is too useful. The module also has power output E+ and E-, which is very suitable for connecting the sensor of the resistance bridge type.
• The module supports differential input, -0.5VCC to +0.5VCC
• Module built-in te...
A Mini weather station based on ESP-12. Include a BME280 or BME680 sensor chip on board, one or more DS18B20 onewire sensors. It's powered by a Lithium cell, can be for short time directly charged over present voltage input. A LDO with very low Iq included. Comes with voltage measurement for the connected battery. Hardware jumper for deep-sleep and a programming connector (charge the battery if +5...
ADS1220 24 bit ADC SPI. Board 40mm x 25mm - ideal to breadboard. Splitet ground, well decoupled with capacitors and ferrite beads. RC filter on all analog inputs.DGND and AGND can be joined together. For better accuracy should be ground plated.
