Abstract: A beverage dispenser ingredient level detection system is disclosed. The system may include a container with a wall, a canister, a capsule, an infrared emitter, and an infrared receiver. The canister may be disposed within the container at a first distance from the wall and may be configured to hold a beverage ingredient. The capsule may be disposed on an interior surface of the wall. The infrared emitter and the infrared receiver may be disposed within the capsule and the infrared receiver may be configured to transmit infrared light rays and the infrared receiver may be configured to detect infrared light rays reflected by the beverage ingredient in the canister to determine whether a pre-determined amount of the beverage ingredient is within the canister. The capsule may absorb infrared light rays that are not indicative of whether the pre-determined amount of the beverage ingredient is within the canister.
