2 pcs PCF8591 módulo convertidor AD/DA de conversión de analógico a digital + Cable

2PCS PCF8591 AD / DA Converter Analog Module to Digital Conversion + Cable Description: Module chip PCF8951. External module voltage input capture (0-5 V voltage input). Three built-in data photoresistor integrated modules through the precise digital AD intensity. Built-in thermistor modules, which captures the exact value of the ambient temperature compared to the AD The built-in five-module module 1 channel 0-5V input voltage (blue potentiometer to adjust the voltage). Modules with indicator light (on the module after power indicator lights) Modules with the output indicator light output DE output indicator output module interface voltage reaches a certain value, the greater the light is more obvious. Characteristics : Operating voltage PCF8591: range 2.5 V to 6 V. Low standby current Through the I2C serial bus input / output. PCF8591 By 3 hardware setting pins Sampling Rate PCF8591 I2C Bus 4 programmable analog inputs as a single or differential input Automatic selection in channel steps. PCF8591 Analog Voltage Range from VSS to VDD PCF8591 integrated circuit 8-bit higher approximation A / D converter Analog power gain How to use the module: Module three red short circuit cap, respectively, the role as follows: P4 connected to jumper P4, select thermistor access circuit. P5 connected to P5 jumper to select the photoresistor circuit P6 connected to jumper P6, to select 0-5V adjustable voltage access circuit.
