​​How do you measure Plant Growth? There are several ways in which plant growth can be gauged, the metrics vary for different types of plants. An apparatus known as auxanometer measures the increase of plant growth. Some other ways of assessing and measuring the plant growth are – measuring the height of the plant, examining the size and number of the leaves, estimating the rate of growth with that of fresh plants and detecting the rate of growth with dried plants. An auxanometer is an apparatus for measuring increase or rate of growth in plants. In case of an arc-auxanometer, there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley which has a pointer attached to it. When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth. The "rate of growth" is a derived measurement obtained by dividing the length of growth measured by the auxanometer, by the time said measurement took. Sensitive auxanometers allow measurement of growth as small as a micrometer, which allows measurement of growth in response to short-term changes in atmospheric composition. Auxanometers are used in the laboratory, the field, and the classroom. Koningsberger invented the  auxanometer.

​​How do Smart Watches measure the Heartbeat on the wrist? The heart rate monitor is based on a difficult to pronounce technology called photoplethysmography, but it basically comes down to using green LED lights paired with light‑sensitive photodiodes to illuminate your skin and measures changes in light absorption. This lets the device detect the amount of blood flowing through your wrist at any given moment. Because blood is red, it reflects red light and absorbs green light. “When your heart beats, the blood flow in your wrist — and the green light absorption — is greater. Between beats, it’s less,” reads the document. The sensor are designed to compensate for low signal levels by increasing both LED brightness and sampling rate. That’s why the heart rate sensor on the back of the device flashes its LED lights hundreds of times per second, helping the device calculate heart rates precisely. But when it measures your heart rate every ten minutes, the Watch switches to using infrared light and if it fails to provide an adequate reading while using the infrared light, the device switches back to the green LEDs. In order for the sensor to work as advertised, the Watch must be close to your skin. The company advises tightening the band in case the sensors aren’t reading your heart rate accurately.
