Hand Mixers:
Hand Mixers are machines that can whisk eggs and cream to solid or mix dough. Hand mixers including just hand mixers and hand mixers with bowl. In addition, hand mixers with bowl can divided into hand mixers with rotary plastic bowl and hand mixers with rotary S/S bowl. Usually, hand mixers with bowl are more convient and effiency, they can not only beat eggs and cream, but also can mix dough and do not to hold the hand all the time.

The aquaculture monitoring system will introduce wireless sensor network technology into large-scale aquaculture to replace cable systems, integrate organically with existing monitoring systems, and construct an intelligent monitoring system for wireless collection and remote control of aquaculture water quality parameters. It is the future of large-scale aquaculture. The development trend.
In view of the unfavorable factors brought about by the large number of applications of on-site cable monitoring systems and the characteristics of large-scale aquaculture farms, each breeding pond is configured as a cluster by modifying the protocol stack, and a fixed set of each cluster is set by modifying the routing protocol. The cluster head method better realizes the communication between the sensor node and the corresponding cluster head and the mutual communication between the cluster heads. According to the situation of fixed clusters and cluster heads in the scene, the clusters are numbered, and the numbers are embedded in the data frames by software, and the positioning of the nodes is accurately achieved. Tests have shown that the data transmission within the system is correct and reliable. The temperature error of aquaculture monitoring system is in the range of ±0.5°C, the error of dissolved oxygen is in the range of ±0.3mg/L, the error of pH is in the range of ±0.3, and it has the advantages of good real-time performance, high reliability and low energy consumption. .
Aquaculture monitoring system is dedicated to large-scale aquaculture
Large-scale aquaculture is very important for real-time monitoring of key environmental factors such as dissolved oxygen content, pH value, salinity, temperature, and turbidity in the culture pond. The aquaculture monitoring system can continuously monitor six water quality parameters. It realizes real-time monitoring and control of multiple key water quality parameters and has certain wireless network data transmission capabilities. Wired systems have led to the use of a large number of wired lines in large-scale aquaculture farms, which has caused messy scenes, complicated data collection and distribution, and can only perform simple, near-distance network control, and system scalability is not easy. Realization therefore limits the further development of the scaled aquaculture industry to some extent.
