เซนเซอร์อุณหภูมิ ความชื้น Grove - Temperature & Humidity Sensor (DHT11)

Grove – Temperature & Humidity Sensor is based on DHT11, which has high measurement accuracy and wide range, and low-cost.

 

Features

High measurement accuracy and wide range: Humidity range of 5 to 95% RH with a ±5% and also a temperature range of -20 to 60℃ with a ±2%.

 

Save the I/O resources of the control board: single-bus digital signal output through the built-in ADC

High Stability and Low Cost

 

Long transmission distance and excellent long-term stability

 

Description

Grove - Temperature & Humidity Sensor using the upgrade version of DHT11, compere to old version of DHT11, the new version of DHT11 is using type of Capacitive sensor, and The measurement range of temperature and humidity is wider than that of the old version, The temperature resolution is higher. DHT11 is the most common temperature and humidity module for Arduino and Raspberry Pi. It is widely favored by hardware enthusiasts for its many advantages such as low power consumption and excellent long-term stability. The single-bus digital signal is output through the built-in ADC, which saves the I/O resources of the control board.
