2 db PCF8591 AD/DA konverter modul analog-digitál

1. A module chip using PCF89512. module supports external voltage input capture (input voltage range 0-5v)3. Three modules integrated photoresistor acquisition environment through the AD intensity accurate numerical4. modules integrated thermistor, can capture the precise value of the ambient temperature through the AD5. The five-module integrated 1 channel 0-5V voltage input acquisition (blue potentiometer to adjust the input voltage)6. modules with power indicator light (on the module after power indicator lights)7. modules with the DA output indicator light board DA output indicator module DA output interface voltage reaches a certain value, the voltage the greater the light brightness is more obvious
