Single unique interface mode DS18B20 needs only one line can be realized by microprocessor and DS18B20 two-way communication in connected with the microprocessor when. The temperature range of - 55~+125 0.5 inherent measurement error. Support multi-point network function multiple DS18B20 can be connected in parallel in three online only only 8 parallel multi-point temperature if the amount is too much will make the power supply voltage is too low resulting in the instability of signal transmission. Working power supply: DC 3~5V
4-channel tracking module used car go black digital signal output adjust the sensitivity for potentiometer each have LED indicator light.
Relay control module 4 independent control active low relay power supply voltage 5V. Each has a corresponding state indicating LED relay indicator light can be directly output signal chip microcomputer control Output using a power terminal can be directly connected 220V devices each control of maximum power 1500W.
The SD card module with the 3.3V regulator chip support 3.3V and 5V system it can be driven by 51 AVR ARM SPI communication mode. At the same time support the SD card Micro card (TF). The use of double row 2 SD card can be used at the same time.
