Introduction

This is universal sensor adapter V2.0, it can be accessed by digital input modules and analog input module. The module with Arduino sensor expansion board, in combination.Improvment compare with the old version,we add a 10K resistor between A & B, A & C respectively,so that you needn't to connect a addition resistor while the sensor must have a pull-up or pull-down resistor. Why need a pull-up or pull down resistor, please refer to"Uderstanding pull-up and pull-down resistors" Generally speaking, this terminal provides a much easier way to connect a switch or any modules that requires pull-up/down resistor to microcontroller

Specifications
• Voltage +5 V
• Current <1000mA
• Size 22x34mm

Pin Out

Understanding pull-up and pull-down resistors

Application with DS18B20

When using temperature Waterproof DS18B20 Digital temperature sensor,need to connect a pull-up resistor for it drived with Arduino microcontroller. The terminal sensor adapter will supply a simple ad stable connection in case without soldering.

Sample Code

Insturciton:

Connection:
1.Plugable Terminal Sensor Adapter & Waterproof DS18B20 Digital Temperature Sensor

A ---->

Blue DATA SIGNAL

B ---->

RED VIN

C ---->

Black GND
2.Waterproof DS18B20 Digital Temperature Sensor & Arduino board
1 A ---->

Digital Pin2
2 B ---->
5V/3.3V
3 C ---->

Setting for the Pull-up Register/Pull-down Register Selection Jumpers When connect DS18B20 with the adapter,please choose to use the Pull-up Register Jumper
#include <OneWire.h>
int DS18S20_Pin = 2 //DS18S20 Signal pin on digital 2
//Temperature chip i/o OneWire ds DS18S20_Pin // on digital pin 2
void setup void Serial.begin 9600 ;
void loop void float temperature = getTemp Serial.println temperature ;
delay 2000 //just here to slow down the output so it is easier to read
float //returns the temperature from one DS18S20 in DEG Celsius
byte data[12] byte addr[8];
if !ds.search addr //no more sensors on chain, reset search Serial.println "no more sensors on chain, reset search!" ds.reset_search return -1000;
if OneWire::crc8 addr, 7 != addr[7] Serial.println "CRC is not valid!" return -1000;
if addr[0] != 0x10 && addr[0] != 0x28 Serial.print "Device is not recognized" return -1000;
