ราคา 95 บาท
Description:
1 module adopts PCF8951 chip
2 module supports external 4-way voltage input acquisition (voltage input range is 0 to 5 v)
3 modules integrated photosensitive resistance, can pass AD gathering accurate numerical value of environmental light
4 modules integrated thermal resistor, can pass AD collection environment temperature precise values
5 module integrated 1 0 to 5 v voltage input acquisition (by blue potentiometer to adjust the input voltage) After
6 modules with power indicator light (for the module power supply indicator goes on)
7 with DA output module, when the module DA output voltage reaches a certain value, DA output indicator light will light up board, the bigger the voltage, the indicator light brightness, the more obvious;
8 module PCB size: 3.6 cm * 2.3 cm
9 standard double panel, thickness 1.6 mm, layout is beautiful and easy, all around has a through hole, the aperture is: 3 mm, convenient fixed
