Seeed Grove DHT11 溫溼度感測器 (升級電容式) | 支援 Arduino & 樹莓派 | 氣象站入門開發

商品說明

DHT11是Arduino和Raspberry Pi最常見的溫度和濕度模組。它具有許多優點，因此受到硬件愛好者的廣泛青睞。
例如低功耗和出色的長期穩定性。可以以非常低的成本獲得相對較高的測量精度。單總線數位訊號通過內置ADC輸出，從而節省了控制板的I / O資源。
最重要的是，Grove 使用DHT11的升級版。DHT11模組的新版本用電容式濕度組件代替了電阻式濕度組件，溫度和濕度的測量範圍更廣，溫度分辨率更高。

Grove – Temperature & Humidity Sensor (DHT11)

Grove – Temperature & Humidity Sensor is a high quality, low-cost digital temperature and humidity sensor based on the new DHT11 module.
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. E.g. Low power consumption and excellent long-term stability. Relatively high measurement accuracy can be obtained at a very low cost. The single-bus digital signal is output through the built-in ADC, which saves the I/O resources of the control board.
On top of that, Grove – Temperature & Humidity Sensor uses the upgraded version of DHT11. The new version of the DHT11 module replaces resistive humidity components with capacitive humidity components, the temperature and humidity measurement range is wider, temperature resolution is higher. You can check the following figure for more detail.
