temperature sensor mysql raspberry pi

20161211· Now that we know how to read the temperature from our DS18B20 sensor, it’s time to save this data to a MySQL server. I would like to point out that for this tutorial, I will not use a PHP page to send and save the temperatures to the SQL server. Here, only a simple request will be used. I have chosen to use a Raspberry Pi Zero and a Mysql server all that is most normal. I also replaced my ...

20160313· The equipment that you will need for this Raspberry Pi temperature sensor is listed below. Keep in mind the breadboard, and the breadboard wire is optional, but I highly recommend investing in these as they may make working with circuitry a lot easier. Recommended. Raspberry Pi. Micro SD Card. DS18B20 Temperature Sensor. Resistor. GPIO breakout kit. Breadboard. …

With the Raspberry Pi and some sensors, it is easy to measure the temperature without much effort. In addition, however, the humidity in certain situations or projects (such as a weather station) can be enlightening. Sensors such as the DHT11 and DHT22 are not only available for a few euros, but they can also measure the temperature as well as the humidity. Accessories. As the sensors already ...

One Raspberry Pi Model A+, one Raspberry Pi 3 Model B and a mobile internet modem or some other way to connect the Raspberry Pi ...

20120726· In my previous post, I showed how to add a realtime clock (RTC) to Raspberry Pi via the I2C bus. Another device that is simple to interface with the Raspberry Pi via the I2C bus is the TMP102 temperature sensor. Technically, its datasheet states "TwoWire Interface", but TWI can be treated as synonymous with I2C in this context.
