Frequent battery replacements are costly and impractical. This includes not only the cost of the batteries themselves but also the labor costs associated with deploying personnel to remote locations, system downtime and proper battery disposal.
High Cost of Ownership
Extreme heat and cold significantly degrade battery performance, leading to unreliable sensor data, reduced capacity, accelerated aging, and potential safety risks.
Temperature Sensitivity
Battery Management Systems add complexity, increase component count, introduce software overhead, and consume additional power.
Complex Design
Improper disposal of batteries can contaminate soil and water, raising sustainability concerns for environmentally conscious agricultural practices.
Environmental Concerns
The logistical and financial burdens of battery management become exponentially more challenging as Agri-IoT deployments scale.
