Passive seismic sensors, for example, use vibrations from tiny earthquakes to track how much oil or water is nearby.
Protein sensors, for example, relay signals from the cell surface to target molecules within the cell.
Additionally, many transmembrane proteins act as sensors; for example, RGT2 and can control transporter expression [ 78].
Various other proteins may also be involved, such as calcium sensors (for example, synaptotagmin, calmodulin (Igarashi & Watanabe, 2007)).
The weather station networks consist of many kinds of sensors [29], for example, image sensors, thermal sensors, moisture sensors, and wind speed sensors.
Take a motion sensor, for example.
Humid atmosphere with CO2 controlled by non-corroding sensor, for example, gold wire or infra-red.
Burbidge notes that some term sheets will have 1-2 clauses that are legally binding (Confidentiality and Exclusivity, for example), so that could be one reason.
Level 2 describes the use of sensors, i.e. for example a sensor network.
In terms of hardware construction, the sensor nodes usually have more sensors than the routing nodes, for example, the dissolved oxygen sensor, PH sensor etc.
