What is it? WH-1201
The wireless (induction) charger is intended for recharging the batteries of cow activity sensors and repeatedly extending their service life.
Reason for creation
The experience of using heat sensors of cows from different manufacturers has revealed that the stated operating time of the sensors does not correspond to reality and sometimes does not exceed 3-5 years. For $130, the sensors need to be replaced with new ones every 3-5 years, which is very expensive.
Comparator LLC has extensive experience in the development of low-power devices with battery and rechargeable batteries. We offers a different approach to solving the problem - the use sensors with built-in batteries and wireless chargers for them.
Where and how is it applied?
The wireless charger is used in agriculture by farmworkers to recharge the sensors of the identification, heat activity, and rumination systems of animals.

The WH-1201 wireless charger has a very simple and reliable design and consists of a plastic case, a PCB, and an induction coil for transferring charge energy through the case and air gaps.
