5 Minute ReadIntroduction This is the second part of a project to build an Arduino-controlled constant temperature enclosure. In the first part of the project we set up the Arduino microcontroller to receive temperature and humidity data from a sensor and then to send this data to a type 1602 liquid crystal display. In this post we […]

4 Minute ReadIntroduction In previous posts the fluxgate magnetometer was described. The frequency pulses from the fluxgate sensor were captured by an Arduino microcontroller then sent to a Raspberry Pi for further analysis and display. One drawback with fluxgates is that they are also temperature dependent. One way to minimise temperature variations is to bury the sensor
