Suppose we want to define a structure for an IoT Environment Monitoring System using the standard ASN$\mathrm{.}1$ module definition. The system consists of multiple sensors and a gateway. The various datatypes related to this application include the following:

A Sensor type consists of an ordered list of the following

sendorId is an INTEGER in the range of $1$ to $100.$

ipAddress is a $4$ bytes OCTETS STRING.

SensorReadings is an unordered list of the $3$ sensor readings which are REAL temperature, INTEGER lightIntensity, and REAL humidity.

An optional sensor status that is either activeMode, sleepMode, or offline. activeMode, is assigned $1,$ sleepMode is assigned $2,$ and offline is assigned $0.$

A Gateway type consists of an ordered list of the following

gatewayId is an INTEGER that takes one of the following values $(222$ or $333$ or $555).$

ipAddress is a $4$ bytes OCTETS STRING.
