Scope: Mainly used in battery (9V or 12V) voltage monitoring, simple and practical, support sound and light alarm. Features: When the buzzer low voltage will "DiDiDi" sounds and the red LED lights up, when the battery voltage rise above to the set value, buzzer will stop alarm. Size: 2.9 x 3 cm The main chip: LM358 9V Battery: When a battery over-discharge (battery voltage drops below about 8V), the red lights and the buzzer calling to achieve sound and light alarm, to achieve control battery discharge status, prevent over-discharge battery, and damage battery; 12V Battery: When a battery over-discharge (battery voltage less than 10.4V), the red lights and the buzzer calling to achieve sound and light alarm, to achieve control battery discharge status, prevent over-discharge battery, and damage battery; Advantages: With a sound and light alarm, simple and practical. The module input with reverse protection, if reverse polarity power input will not burn. But without overvoltage protection, if the input exceeds 15V, the chip above the module will burn out. Adjustment method: 9V Battery: Input 9V, the LM358 voltage adjustment between 2 feet and 4 feet to about 5.78V, the alarm voltage is 8V (we has set it before shipment, so you don't need to adjust it again). Clockwise adjustment, 2 feet and 4 feet voltage is reduced, the sensitivity increased. 12V Battery: Input 12V, The LM358 voltage adjustment between 2 feet and 4 feet to about 6.05V, the alarm voltage is 10.4V (we has set it before shipment, so you don't need to adjust it again). Clockwise adjustment, 2 and 4 feet voltage is reduced, the sensitivity increased. Package includes: 3 x Battery Over-discharge Protection Module

Description: LED Carbon Monoxide Tester Poisoning Smoke Gas Sensor Alarm Warning Detector The photoelectric detector detects the smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The chamber can shield external light,but don't affect the smoke into it. While have no smoke,the diode can receive very weak infrared light. Features: *Test by hand. *Auto reset. *Asic adopted. *Anti-light. *Strong adaptability circumstance. *SMT design,High stability. *All-round detection angle *Suitable for Home, Office, Hotel, etc. Specification: Product Name: photoelectronic smoke detector Operating voltage: DC 12V (network type) 9V Battery (independence or wireless type) Wireless transmission distance: ≥150m Static current: ≤200uA (network type) ≤10uA (independence or wireless type) Alarm current: ≤20mA Indicate alarm: Red LED Flash Sound level: ≥85dB/m (independence or wireless type) Operating temperature: -10°C~+50°C Operating humidity: ≤95%RH Detecting Area: 20 square meter Installation height: ≥6m Alarm Output: sound&flash alarm (independence type) Rfsignal 315MHz-433MHz (wireless type) Size: 106x35mm Color: White Weight: 121g Package includes: 1 x Photoelectronic smoke detector (with accessories) 1 x Manual for photoelectronic smoke detector 2 x Expansion Plugs 2 x Screw Details pictures:
