This App measures spot temperatures in the same way that temperature guns are used in COVID-19 testing stations and at airports. It uses a sensor which measures the infrared energy transmitted from a surface. It allows you take as many readings as you like, and stores the measured values of both ambient and surface temperature for each reading in its …

This uses the DHT11 sensor to measure temperature and humidity and display the apparent temperature. It can also display wind speed if connected to an AustSTEM designed anemometer which can be assembled in class from cardboard, a fidget spinner, and an optical sensor. Directions Step 1: Setup Set up the app by plugging a DHT11 sensor into P2. If available, …

This measures, logs, and transmits temperature (T) and relative humidity (RH) data using either the popular DHT11 sensor or the slightly more expensive (but with better specifications) DHT22. Directions Step 1: Setup Set up app by plugging either a DHT11 or DHT22 sensor into P2. The DHT11 is the blue sensor on the left below.     Step 2: Running …

This measures heart rate at rest or after exercise. Pulse rate is an indication of your heart rate as your arteries expand each time the ventricles pump blood out of the heart. Directions Step 1: Setup Set up the app by plugging the Heart Rate Monitor sensor into P4. Hold the sensor against the skin on  the inside of the …

This measures, logs, and displays instantaneous acceleration using its on-board accelerometer. Suggested usage is not to throw the Kookaberry about as it will get damaged.  Instead, it can be dropped carefully on a padded surface; held whilst you jump on a trampoline; go on a swing; go down a slippery dip; go on a seesaw; and run or hop. The …

This senses the level of the ambient light and, if too dark, switches on a light (LED). Directions Step 1: Setup Setup the app by plugging an ambient light sensor into P4 and an LED into P2. A cardboard house can be constructed, with the sensor mounted on the roof and the LED in a window.       Step …

This measures moisture in soil (or any other medium) using a resistive or capacitive soil moisture sensor.  When the moisture falls below an adjustable threshold level. a control signal is sent to a relay which connects power from a separate battery to a 3v mini-pump. When the moisture level rises to above the threshold level, the pump is switched off.   …
