Overview
The MKR THERM Shield allows a board of the MKR family to acquire temperatures from a thermocouple of type K and a DS18Bxx digital one wire sensor. The Thermocouple is a kind of temperature sensor that offers high accuracy and a wide range of measured temperatures. Its analog nature requires specific interfacing and this shield relies on the MAX31855 thermocouple digital interface.
The two connectors of the MKR THERM Shield allow the usage of Type K thermocouples with or without a plug attached to the metal wires.
The MKR THERM Shield has its own library to read the temperature measured by the thermocouple. You may find further details and a usage example in our Getting Started page.

Home monitoring is a big part of home automation, but it's often overshadowed. Our attention tends to get hijacked by cool projects that perform physical actions. Whether it's turning the lights on, changing their color, running a robot vacuum cleaner, pulling on the blinds or watering the garden. All these actions are very cool and very visible. Which makes it easy to ignore the background tasks that are the backbone of great home automation. YouTuber and robotics maker RootSaid has been giving this a lot of thought. He's put together an excellent tutorial on creating a self contained, real-time home monitoring module. It's built around the excellent Nano RP2040 Connect, and sends everything to Arduino Cloud. Home Monitoring for You, and Your Family His objective was to create a compact bundle of sensors to keep an eye on various conditions around the home. This battery powered system can then be positioned anywhere, and monitored from Arduino Cloud. His idea is to install the module in an elderly relative's home. That way, he can keep an eye on their environment from anywhere. Of course, this doesn't have to be used purely as a care system. That's a great application for his environment monitoring platform, but it's just as useful for your own home automation system. Too often, sensors (temperature, for example) are physically connected to other automation devices, like Wi-Fi mains switches. But chances are you want to know the temperature over by your sofa. Not down the back of the TV cabinet. RootSaid to the rescue. A Compact Home Automation Sensor Module Let's take a look at the sensors bundled into this compact package. He's got an LDR in there to monitor the light levels. This is perfect for bigger home automation projects, as it can trigger lights all around the house. Even outdoor lighting, if you wanted. There's a Bosch BME280 to keep an eye on the environment. This is becoming a popular device among the home automation crowd.
