M2M is the one- or two-way exchange of information between devices, using either wired or wireless connectivity without the manual assistance from humans.
An IoT sensor like a thermostat can be used to monitor the temperature at all times. The same way, many other IoT sensors can be used that monitor pH level and other important attributes of stored goods. With the right type of M2M connectivity, the information can be relayed to the server. Depending on the condition of products, the values of various environmental factors can be controlled. The IoT development can be done in such a way that it optimizes the whole process. So, there is never a situation where an iota of extra energy is used. It is a great way to conserve energy.
