HIP9011AB General Description

The HIP9011 is used to provide a method of detecting premature detonation often referred to as "Knock or Ping" in internal combustion engines. The IC is shown in the Simplified Block Diagram. The chip can select between one of two sensors, if needed for accurate monitoring or for "V" type engines. Internal control via the SPI bus is fast enough to switch sensors between each firing cycle. A programmable bandpass filter processes the signal from either of the sensor inputs. The bandpass filter can be selected to optimize the extraction the engine knock or ping signals from the engine background noise. Further single processing is obtained by full wave rectification of the filtered signal and applying it to an integrator whose output voltage level is proportional to the knock signal amplitude. The chip is under microprocessor control via a SPI interface bus.

These are uv leds. Different from those presented in the photo to the product. Purple leds should have a fill not transparent, but with a slight shade of pink/purple.

The order corresponds to the description, everything is workable, the order was delivered to the central federal district 32 days considering may holidays. The seller poisoned the order by simple international shipment, although avaq saver shipping was paid. Decide to order from this seller or not.
