Spray dispenser activated by sensed light level

摘要

A dispenser incorporates, or can receive, a containment portion holding a quantity of dispensable material (e.g., a pesticide). The dispenser has an indicator and a sensor, which can sense a level of light in an environment immediately surrounding the dispenser. The dispenser is formed such that when it is in use it can be set to dispense the dispensable material in response to the sensor sensing a predetermined level of light. The dispenser is formed such that once it is activated to dispense the dispensable material it cannot be deactivated until the dispensable material has been dispensed in accordance with settings of the dispenser, and when the dispensable material has been dispensed in accordance with the settings the indicator indicates that this has occurred.

1. A dispenser adapted to receive a containment portion holding a quantity of dispensable material, the dispenser having a circuit board, an indicator means, a valve adapted to be connected to the containment portion, and sensing means that senses a level of light in an environment immediately surrounding the dispenser, wherein the circuit board controls dispensing of the dispensable material by a cycle of dispensing that includes opening and closing the valve at predetermined intervals and the sensing means is electrically connected to the circuit board, wherein the circuit board is activated in response to a signal transmitted to the circuit board in response to the sensing means sensing a predetermined level of light such that once the circuit board is activated in response to the signal it cannot be deactivated until the dispensable material has been dispensed in accordance with the cycle, and wherein when the dispensable material has been dispensed in accordance with the cycle the indicator means indicates that this has occurred.
