Sometimes tilt sensors are incorrectly called inclinometers because the sensors simply generate a signal (as opposed to inclinometers that generate a reading and a signal). A basic circuit using a tilt sensor is shown here. For this assembly, the components used are: a tilt sensor, a 470 Ohms resistor, a LED and a 3V power supply.

If an irradiance sensor is placed in POA, it must be placed at the same tilt angle as the PV module, either by attaching it to the module itself or with an extra platform or arm at the same tilt level. Checking if the sensor is properly aligned can be done with portable tilt sensors or with an integrated tilt sensor. [7]
An inclinometer sensor's true or absolute accuracy (which is the combined total error), however, is a combination of initial sets of sensor zero offset and sensitivity, sensor linearity, hysteresis, repeatability, and the temperature drifts of zero and sensitivity—electronic inclinometers accuracy can typically range from ±0.01–2 ...
Pressure sensors, also known as barometers, measure relative and absolute altitude through the analysis of changing atmospheric pressure. Pressure sensors can be used in consumer devices for sports and fitness or location-based applications where information on elevation can be valuable.
A significant drawback of a resistor sensor is the unavoidable electrical connection between the current to be measured and the measurement circuit. An isolation amplifier can provide electrical isolation between measured current and the rest of the measurement circuit. However, these amplifiers are expensive and can also limit the bandwidth ...
This was a simple arrangement of two water pots, connected by a long water-filled tube. Any change in tilt would be registered by a difference in fill-mark of one pot compared to the other. Although extensively used throughout the world for Earth-science research, they have proven to be quite difficult to operate.
The open-circuit time constant (OCT) method is an approximate analysis technique used in electronic circuit design to determine the corner frequency of complex circuits.It is a special case of zero-value time constant (ZVT) method technique when reactive elements consist of only capacitors.
