W1209 Digital Temperature Controller:
The W1209 is an incredibly low cost yet highly functional thermostat controller. With this module, you can intelligently control power to most types of electrical device based on the temperature sensed by the included high accuracy NTC temperature sensor. Although this module has an embedded micro controller no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on board relay can switch up to a maximum of 240V AC at 5A or 14V DC at 10A. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
This is a 12V 1A Power Adapter with 4.2mm and 2.7mm double male barrel jack connector. It comes in a black plastic enclosure with long two core wire. The power adapter is durable and can accept 100-240V AC supply with 50/60Hz. It comes with a small led indicator to check the state of Power Adapter.
3 inch - 12V - DC Cooling Fan:
This Brush-less DC Cooling Fans are operating at 12V with a dimension of 80x80mm. They are typically found in ATX Computer cases, servers, and other enclosed equipment but they can also be used in a variety of other projects requiring moderate airflow. The fan spins at ~2600 RPM and can move approximately 30CFM. It is fairly quiet – just 30.7dBA. There are two connectors commonly found in PCs on the end – a 4 pin Molex connector designed to fit in line with older style hard drive connectors and a smaller 3 pin Molex KK 2.54mm that is compatible with our 3 pin Molex Header. To use the fan, simply connect Red to 12V, Black to Ground. The White wire is a Tach signal – it can be used to monitor the fan rotation or left disconnected if it isn’t needed.
DC Female jack:
This is a DC Female Jack Connector with Wire. It has many applications. It can be used for any 3 to 24 volt up to 5 Ampere applications. It can also be used to replace the damaged adapter cable 5mm dc female connector.
DC Crocodile Alligator Clip Black and Red Pair:
Alligator clips are frequently used in school physics laboratories to quickly and cheaply assemble circuits. They are useful for connecting components to wires. Alligator clips can be used as miniature clamps to hold parts together for gluing and wires together for soldering.
Temperature fluctuates a lot.For eg. i have set 37.7 in programme 0 in heat mode.Programme 1 as .2. light will turn on and off very often which is not as .2 difference relay.
