This intelligent non-contact liquid level sensor uses capacitive sensing to detect liquid presence through container walls, eliminating direct contact with corrosive, viscous, or contaminated liquids. The sensor compensates for residual films, moisture, or foam in liquids such as milk, honey, latex, blood, engine oil, and acid/alkaline solutions, delivering reliable level detection. A builtin LED indicator shows realtime status, and the IP67rated PCV0 housing ensures stable operation in harsh industrial or outdoor environments. This sensor works seamlessly with Arduino and other 5V logic microcontrollers.
OneTouch Automatic Sensitivity Calibration
The sensor features an intelligent sensitivity memory function with external pushbutton control. Simply ensure liquid is present at the sensing position and singleclick the button. Within 35 seconds, the sensor automatically locks onto the optimal sensitivity for the current container wall thickness and material. This eliminates manual tuning and adapts to plastic, glass, or ceramic containers up to 10mm thick.
NonContact Detection for Demanding Liquids
Because the sensor mounts on the outer container wall, it never touches the measured liquid. This avoids corrosion from strong acids or alkalis, prevents contamination in medical or food applications, and eliminates fouling from sticky substances like honey, latex, or engine oil. The noncontact design also simplifies cleaning and maintenance in hygienic environments.
Penetrates NonMetallic Containers with High Sensitivity
The advanced capacitive sensing technology works through plastic, glass, and ceramic walls with a sensing distance (wall thickness) up to 10mm. It detects lowconductivity liquids (≤50ms) and compensates for residual moisture or foam that would confuse ordinary sensors. The builtin highprecision IC converts minute capacitance changes into a reliable high/low level signal.
IndustrialGrade Robustness
The housing is molded from PCV0 fireretardant material, and the IP67 waterproof rating protects against dust and temporary immersion. An onboard LED indicator provides instant visual confirmation of liquid presence. With an operating temperature range of 25°C to +85°C and temperature drift below 20%, this sensor performs reliably in refrigeration, outdoor tanks, and industrial machinery.
From water shortage protection in household dispensers and coffee machines to liquid level monitoring in medical equipment and strong acid/alkali storage tanks, this noncontact sensor delivers corrosionfree, maintenancereduced level detection. It also suits sealed chemical containers and toxic liquid monitoring where any leak would be hazardous.

Receipt of deliveries
Deliveries to post office boxes are not permitted where delivery is by courier. If delivery is by courier and nobody is available at the delivery address to accept delivery when delivery is attempted then the courier may either:
- leave the relevant parcel at the unattended address (the courier will do so if specified in your delivery requirements); or
- re-attempt delivery at a later time or date, in which case we may charge you an additional re-delivery fee.
Note that if a delivery is left unattended at the shipping address and is subsequently stolen then the theft is your responsibility, not ours.
