Arduino 範例

#include <Wire.h>

#define ADS 0x40
#define MT_CMD 0xe3 //using hold master mode, requesting temperature
#define MRH_CMD 0xe5//using hold master mode, requesting humidity

void setup() {
  // put your setup code here, to run once:
  Wire.begin();
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  byte temp_l,temp_h,humd_l,humd_h;
  uint16_t temp,humd;
  float T,RH;
  //get temperature
  Wire.beginTransmission(ADS);

數字濕度感測器 SHT20 採用(RH / T)

用於各種應用,並已成為行業標準

數字 SHT2x 採用濕度傳感器系列是大批量使用在各種各樣的應用程序,並已於今天成為事實上的行業標準。所述SHT2x採用系列包括一個低成本版本與SHT20濕度傳感器,一個標準的版本與所述SHT21濕度傳感器,和一個高端版本與SHT25濕度傳感器。打開腔模包 – 它封裝除了濕度傳感器區域的完整的芯片 – 保護免受外部衝擊的電容式濕度傳感器,並促進良好的長期穩定性。在對SHT2x傳感器是在大,小體積都可用。

Digital Humidity Sensor SHT2x (RH/T)

Used For A Variety Of Applications And Has Become The Industry Standard

The digital SHT2x humidity sensor series is used in high volumes in a wide variety of applications and has today become the de facto industry standard. The SHT2x series consists of a low-cost version with the SHT20 humidity sensor, a standard version with the SHT21 humidity sensor, and a high-end version with the SHT25 humidity sensor. The open cavity mold package – which encapsulates the complete chip except for the humidity sensor area – protects the capacitive humidity sensor against external impact and facilitates excellent long-term stability. The SHT2x sensors are available both in large and small volumes.

 

Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out on command. Furthermore, the resolution of the SHT2x humidity sensor can be changed on command (8/12 bit up to 12/14 bit for RH/T) and a checksum helps to improve communication reliability. With this set of features and its proven reliability and long-term stability, the SHT2x humidity sensor series offers an outstanding price-performance ratio. To test a humidity sensor from the SHT2x series, two evaluation kits, EK-H4 and EK-H5, are available.
