This is a powerful sister version of our Grove - Temperature&Humidity Sensor Pro. It has more complete and accurate performance than the basic version. The detecting range of this sensor is 5% RH - 99% RH, and -40°C - 80°C. And its accuracy reaches up to 2% RH and 0.5°C. A professional choice for applications that have relatively strict requirements.
This code is for
- Grove - Temperature&Humidity Sensor Pro
- Grove - Temperature & Humidity Sensor (DHT11)
- Grove - Temp & Humi Sensor v1.0 (DHT10)
This driver depends on:
This is easy to install with the following command.
curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s - On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install seeed-python-dht To install system-wide (this may be required in some cases):
sudo pip3 install seeed-python-dht To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install seeed-python-dht First, Check the corresponding gpio number of the board:
pi@raspberrypi:~/Seeed_Python_DHT $ grove_gpio Hat Name = 'Grove Base Hat RPi' <pin> could be one of below values in the pin column for GPIO function And connect the device to corresponding slot ============== pin | slot ============== 5 | D5 12 | PWM 16 | D16 18 | D18 22 | D22 24 | D24 26 | D26 Next, initialize the sersor object:
import seeed_dht # for DHT11 the type is '11', for DHT22 the type is '22' sensor = seeed_dht.DHT("11", 12)DHT10 uses i2c protocol, So there is no need to specify an extra pin.
Just add contents below:
import seeed_dht # for DHT11 the type is '11', for DHT22 the type is '22' sensor = seeed_dht.DHT("10")To read from the sensor:
humi, temp = sensor.read() print('DHT{0}, humidity {1:.1f}%, temperature {2:.1f}*'.format(sensor.dht_type, humi, temp)) If you have any good suggestions or comments, you can send issues or PR us.
