Thin Film Sensor Output Signals: Voltage vs Digital Explained
There are two categories of thin film sensor output signals: voltage and digital. They also pass signals that allow information to be transmitted from the sensor to other devices, such as a computer. Knowing the distinction between these two signals is crucial for you to be able to select the appropriate one for your need.
Benefits
Typically, thin film sensors signals are dealt with in voltage. Voltage signals are analog — that is, they can fluctuate and express a wide range of values depending on what the sensor is experiencing. This type of signal is common in older technology, and can be effective in specific use cases.
Digital output signals are not purely voltage signals. Digital signals are binary, meaning they have only two values: high or low. These signals are represented as ons and offs is more easy to handle and understand than the use of voltage signals.
Examining voltage and digital signals in thin film sensors can help determine which is right for you. Voltage signals can get a broader spread of values, which can be beneficial for accurate measurements. But compared to digital signals, they can be more susceptible to noise or even a deliberately disruptive signal.
Advantages
Digital output signals, on the other hand, are robust and powerful enough to transmit sensor data. They are less influenced by externalities and can work more seamlessly with other digital systems. Making digital circuits better when precision and stability are paramount.
Digital output signals are advantageous in the sensor field. A big plus is that they can easily be hooked up to digital devices, such as computers. This ensures faster and easier data processing and enables you to cooperate with other systems.
Summary
In addition, force sensitive resistor digital signals are more accurate and reliable as compared to voltage signals. And due to the nature of digital signals, we don’t have to worry about quality loss from distance or from interference caused by external forces. This can result in better or more accurate sensor measurements.
When it comes to selecting voltage versus digital output signals out of thin film sensors, ultimately it all comes down to what you need. Voltage signals can represent a greater range of values, but digital signals are more robust and easier to work with. The differences between these two types of signals is ultimately what will allow you to make the smart decision that is best for you.
