Features:
This circuit uses a temperature sensor DS18B20 do 3 common anode digital tube to do the show, AT89C2051 microcontroller to do processing control circuit is simple.
X1 access 5V ± 0.5V DC power supply (Note that the positive and negative)
click the S1 circuit displays the current temperature value, click S1 to enter the temperature setting, then press S2 or S3 to adjust the set temperature value, S1 is pressed again return to the current temperature display at the same time be the set temperature to save this setting will be saved in DS18B20 not lost power after the next power-up, the MCU will automatically read into the last the temperature setting value.
Press S1 to turn off the display and temperature control, again pressed on again. The circuit also designed a way to control the output LED1 is light when the current temperature exceeds the set temperature.
output voltage of 5V from X2, can drive 5V relay.

Purchasing & Delivery

Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.
Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.
Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.
In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
