The invention relates to a fuel injector electromagnetic valve control method and device, computer equipment and a storage medium. The method comprises the steps that the method is applied to an electromagnetic valve driving circuit, a follow current path of fuel injector driving current is changed into an NMOS tube from a traditional diode, heat loss of a follow current diode in a conventional control method can be reduced, part of energy in an electromagnetic valve coil of the fuel injector can be recycled by changing a switching mode, the energy utilization efficiency is improved, and the energy utilization rate is increased. And by controlling the opening state of each NMOS tube, reverse current driving is applied to the electromagnetic valve of the oil injector after forward current driving is completed, and the demagnetization effect in the electromagnetic valve of the oil injector can be improved by adopting the method.

The invention relates to a humidity sensor based on a nickel-cobalt-phosphorus hollow nano material. The humidity sensor comprises a humidity sensor body with an interdigital electrode as a substrate and the nano material located on the surface of the interdigital electrode. The nano material comprises the following components: 10 to 20 mg of hollow coralline nickel cobalt phosphorus, 1 to 2 mL of isopropanol and 7.5 to 15 [mu] L of naphthol diluted with isopropanol. The hollow coralline nickel cobalt phosphorus comprises the following components: 0.3 g of Ni (NO3) 2.6 H2O, 0.3 g of Co (NO3) 2.6 H2O, 0.1 g of Ag2WO4, 1 g of PVP (polyvinylpyrrolidone), 1 g of urea, 10 mL of deionized water and 70 mL of absolute ethyl alcohol. According to the humidity sensor based on the nickel-cobalt-phosphorus hollow nano material, the problems that an existing common humidity sensor is generally small in application range, poor in material performance, not novel in material and the like can be solved.
