Charge transfer caused by objects with different electrostatic potentials close to each other or in direct contact
ESD is a common near-field hazard source, which can form high-voltage sources, arc electric fields, instantaneous large currents, and accompanied by strong electromagnetic radiation, forming electrostatic discharge electromagnetic pulses
Current>1A
Rise time～15ns, decay time～150ns
Electrostatic discharge has mechanical effects, thermal effects, strong electric field effects, and electromagnetic pulse effects, which will have a great impact on smart door locks, causing damage to components and abnormal functions.
The damage of static electricity is concealed, latent, random, and complex, causing immeasurable losses to enterprises and production. So to avoid this loss, there must be adequate anti-static measures
1. Media isolation
2. Shield
3. Grounding and grounding
4. Others such as the use of ESD protection devices, etc.
