The DS1624 consists of two separate functional units: a 256-byte nonvolatile E2 memory and a direct-to-digital temperature sensor. The nonvolatile memory is made up of 256 bytes of E2 memory. This memory can be used to store any type of information the user wishes. These…
The DHt12 is an upgraded version of the classic DHT11 humidity temperature sensor, it is fully downward compatible, more precise and adds an I2C interface. Features: compact size low power consumption low voltage operation Standard I2C and 1-wire interface. Sensing range Temperature: -20 ~ +60…
The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector. The host can query the LM75 through its I²C interface to read temperature at any time. The open-drain overtemperature output (OS) sinks current when the programmable temperature limit is exceeded. The…
The HDC1008 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The device measures humidity based on a novel capacitive sensor. The humidity and temperature sensors are factory calibrated. The sensing element of the HDC1008 is…
This is follow on from the DS18b20 terminal example at http://www.pibits.net/learning/120.php , this time a python example Code [codesyntax lang=”python”] import os import glob import time os.system(‘modprobe w1-gpio’) #load one wire communication device kernel modules os.system(‘modprobe w1-therm’) base_dir = ‘/sys/bus/w1/devices/’ #point to the address device_folder = glob.glob(base_dir…
Connect a DS18b20 temperature sensor to your Raspberry PI as follows. I used a breakout for this. In this example we will just be using terminal commands Now you need to enter the following at the command prompt: [codesyntax lang=”bash”] sudo nano /boot/config.txt [/codesyntax] to open…
